Zelda, Sabrina, and Ambrose welcome Gryla, Pesta, Sycorax, Dezmelda, Mother Hubbard, and Mambo Marie, who claim they were summoned against their will. Zelda explains that none of them are safe on their own with the arrival of a community of pagans, including a Gorgon and the great god Pan. Mambo Marie advises her fellow witches to at least hear the Spellmans out as opposed to attacking them. They face a common enemy and are forced to unite in order to survive. Zelda pleads with Gryla to hear her out and tells Sabrina to fetch them some food and drinks.
Dr. Cerberus and Hilda watch the Addams Family in his basement. Hilda says that she prefers The Munsters, and the TV cuts out. Dr. Cee goes to fix it and sees Hilda’s mutated face beneath her glamour, though he makes nothing of it, writing it off as too much TV. Hilda and Dr. Cee then decide to rehearse their number for the Sweeney Todd audition.
Gryla points out that the Church of Night has always turned their kind, hedge witches, away. For centuries, they've had to brave the wilderness alone. She questions why she should help them. Zelda explains that their numbers are depleted. Their magicks non-existent. They need strength, and if the wayward witches agree to help, the Academy could be their home too. They could make a new coven together. Mambo Marie admits that there is wisdom in what she says. Better to be united for what is coming. As for the Dark Lord, he’s still at large but trapped in a flesh Acheron, with his strength muted. Zelda asks that the witches stand with them against the pagans when they come in three days. She tells Pesta to poison the soil around the Academy so if any pagan touches it, they'll shrivel with disease. As for sleeping quarters, Zelda has arranged for them to stay at the Desecrated Church and tells Sabrina, Prudence, and Nick to prep it.
Lilith receives word from her demonic minion that after searching all nine circles, the Dark Lord is nowhere to be found. However, he did send Lilith a message in the form of a fetish doll. The same doll she was gifted by Adam Masters. Lilith concludes it’s a warning from the Dark Lord that he’s on his way to seek revenge for her usurping him and imprisoning him. She orders her minion to pack her belongings, as she must seek safe haven before he manages to separate from Blackwood.
Prudence confronts Nick and Sabrina as the three of them prepare the Desecrated Church for the hedge witches. They reveal that they’ve broken up and are only friends. Prudence tells Sabrina that her mortal side is showing and that heartbreak isn’t a good look for witches. She offers to make the pain go away with a cord-cutting spell. All they need is two candles joined by one wick, and whatever emotional ties Sabrina has with Nicholas will be burned away for good. However, Sabrina hopes that their breakup is temporary and that they will get back together. Prudence says that Sabrina and Nick were a mismatch from the start. She asks if Nick ever thanked Sabrina for saving his life and helping him get clean, which he didn’t. Sabrina turns down Prudence’s romantic advice and leaves.
Ambrose convenes with the hedge witches (Gryla, Pesta, Sycorax, Dezmelda, Mother Hubbard, and Mambo Marie) to collect their information. First up is Gryla of the Mountains. Single mother of thirteen Yule lads, with another on the way. Moving onto Sycorax. Ambrose confirms that she’s a river witch and asks what she is capable of. She reveals that she could drown Ambrose where he stands. A remarkable gift that will come in handy against the pagans.
Sabrina arrives at Harvey’s to find him, Theo, and Robin covered in mud. They reveal that Circe turned Billy, Carl, Martin, and Eric into pigs. Robin also reveals that he’s a pagan and that they’re planning a slaughter that he will not be party to. He doesn’t want what they want. The pagans came to Greendale to resurrect the pagan gods, starting with the oldest ones, the Green Man. Sabrina asks Robin how do they stop them. Robin reveals that the ultimate resurrection of the Green Man can’t happen without a virgin sacrifice. Which is why Robin got close to Theo and Nagaina got close to Harvey. Roz is the only one not a virgin, which is why they turned her to stone, as well as because she could use her cunning to stop them. Robin reveals that when the Green Man’s head scrapes the sky and the ripe fruit falls from his arms, he’ll be resurrected. Caliban interrupts to propose a deal. He knows of a Pygmalion spell that would turn Roz back to flesh. And if Sabrina comes with him to find the spell, he’ll outline his proposal to her. Sabrina agrees and leaves with Caliban. Mr. Kinkle then calls Harvey into the house for dinner.
Hilda and Dr. Cerberus rehearse their number for Sweeney Todd. Hilda’s glamour suddenly wears off and Dr. Cerberus sees her mutated spider form. He panics and backs into a corner. Hilda pleads with his to relax and listen to what she has to say.
As Sabrina and Caliban search for the spell to save Roz, Sabrina questions why it’s called a Pygmalion spell. Caliban tells Sabrina about the myth of Pygmalion. He was a sculptor who carved a woman made of ivory. Pygmalion fell in love with the statue, wished her alive. He made an offering to the gods, promised he would give up his greatest love, sculpting. In exchange, when Pygmalion kissed the statue, she turned to flesh. As for Caliban’s proposal, they could compete against each other to find the third item of the Unholy Regalia, Judas' pieces of silver, or they could work together to find them. They would both win the throne in that case. They could align and rule Hell together and get married. Sabrina turns him down. So, he asks her to make him a counteroffer. And in return, he’ll give her the spell he just found. Sabrina negotiates with Caliban, starting with making Earth off-limits and ending the enslavement of all souls. She’d like to reform the Hell that already exists, make it better, work with Heaven instead of against it, though Caliban is doubtful it is possible. Sabrina agrees to Caliban’s proposal, but she demands it in writing first and informs him that their alignment would be strictly political.
Lilith arrives at the Academy in search of safe haven from the Dark Lord. However, Zelda informs Lilith that they’re more concerned with the pagans at the moment. Lilith offers to help, but Zelda doesn’t trust her and turns Lilith away. Lilith, no longer seeking the help of the Church of Night, realizes she needs the help of a good Christian if she's to hide from Lucifer.
Sabrina and Caliban return to Harvey’s to find him scrambling to put back together the pieces of Roz. She’s been shattered, broken into a million pieces. Caliban tells Harvey that Roz needs to be put back together and arranged into her correct shape, as he knows of a special epoxy that can hold her together. Sabrina asks about Harvey and Roz and why they haven’t had sex. Harvey tells Sabrina that they were planning to, but the carnival came and things got bad again. Sabrina then reveals to Harvey that she never had sex with Nick and that they broke up. She comments that maybe he wasn't the right one.
Hilda explains to Dr. Cerberus that she’s suffering from a pagan curse and that she thinks she’s going to die. Dr. Cerberus refuses to accept this is Hilda’s fate and promises her a quiet life in the countryside. He wants to call Zelda for help, but Hilda stops him, claiming that there’s no saving her. She simply wanted to spend her last moments with Dr. Cerberus. He asks if there’s anything he can do to make her more comfortable. Hilda tells him that she’s craving a hamburger and milkshake from a diner in Riverdale.
Prudence assists Mambo Marie as she teaches the coven a Haitian dance of protection. However, they are interrupted by Zelda, who is not pleased nor is she amused. Zelda calls Prudence into her office to scold her. Prudence informs Zelda that Mambo Marie is no stranger. Prudence and Ambrose met her in New Orleans. She helped them find Blackwood. It was Prudence who invited Mambo Marie to Greendale. Separate from the summoning. She just happened to arrive at the same time as the hedge witches, but she is certainly not one of them. They are in the fight for their lives against the pagans, and if they’re going to survive it, they’ll need to adapt, Prudence explains, after having witnessed Mambo Marie’s magick firsthand. She doesn't get power from the Dark Lord, she gets it from somewhere else, and if they could learn where, maybe they too could gain power. However, Zelda is stuck in her ways. Never in the history of the Church of Night has an outsider been allowed to lead a ceremony. Prudence accuses Zelda of only inviting the hedge witches because they can't challenge her status. Zelda explains that Mambo Marie is Catholic.
Mambo Marie interrupts and apologizes if Zelda was frightened by her ceremony. She promises that the only spirits she invites in are the ones she knows and trust. She introduces herself as Mambo Marie LeFleur, Vodouisant of the Fourth Ward. She takes Zelda’s hand and sees her mèt-tèt. He is beautiful and powerful. While it is true, Prudence invited her, Mambo Marie has been waiting for an invitation all her life. Her mèt-tèt told her, long ago, that something was coming. Something very old and very evil and that if she could summon her courage, she might play a role in helping to beat it back. Zelda admits that she’s wary of newcomers but is in no position to refuse help and asks her to stay, as their honored guest.
Sabrina, Harvey, and Caliban have gathered every piece of Roz. Before they can glue her back together, they must take her to the place that Harvey and Roz first kissed, where the spell will be most effective. Harvey reveals that was at school. The night of the dance. Theo and Robin arrive and offer to help carry Roz.
A member of the Southside Serpents enters Cerberus Books. Hilda tells him to go away, but he doesn’t. Walking further into the store and demanding to be serviced. He walks right into Hilda's web. She pulls him up and feasts on him.
Sabrina, Harvey, Caliban, Theo, and Robin take Roz to Baxter High, where they glue her back together. Harvey must now say the spell, but first, he has to make his offering to Aphrodite or Eros. Caliban explains that Harvey has to offer up his love for Rosalind in order for her to be restored to flesh. Aphrodite is the goddess of love. She’ll grant Harvey’s wish but demands his heart's desire. He has to forsake his truest love and kiss her to complete the spell and restore her to flesh. However, if Harvey ever betrays his vows and kiss Roz again, she’ll turn to stone forever. Harvey recites the vow to Aphrodite and kisses Roz, but she doesn’t turn back. Caliban explains that Harvey’s offering was rejected because Harvey doesn’t truly love her. Aphrodite will only accept his heart’s truest desire and that must not be Roz. Harvey gets angry and punches Caliban. Robin informs the group that Circe has powerful magicks of transformation, and she could turn Roz back into flesh. He neglected to tell them this because it’s too dangerous. Circe could turn them into any creature she’d ever seen before. And without magick, they’re no match against her. However, Sabrina knows where they can borrow magick.
Mary Wardwell receives a knock at her door. Unbeknownst to her, it’s Lilith posing as Adam. He tells Mary that someone is after him and that he needs for her to hide him with her goodness as a faithful Christian woman. Mary says that she loves Adam and that she’ll protect him.
Sabrina returns to the Academy with Caliban, where she asks Prudence for Ambrose’s whereabouts. There, she is confronted by Nick, who accuses her of moving on with Caliban. Sabrina explains that he’s only helping her save Roz and that she’s never lied to Nick, unlike him, who's lied to her constantly, that is when he wasn’t cheating on her. Even Prudence chimes in to add that Sabrina is right. While Sabrina is sorry for what he endured, she tells Nick that he’s neither a martyr nor innocent. And if he ever disrespects her again, then he can forget about them being friends.
Dr. Cerberus returns to the shop to find that Hilda has killed a man. She tells Dr. Cerberus that she’s not dying. She just needed blood, which has only made her lustier. She slowly approaches him and tells him about the eggs inside of her, waiting to be fertilized.
Sabrina and Caliban go to the Academy's library in search of Ambrose. She dismisses Caliban as she finds him. Sabrina has been thinking about the hedge witches and the stone circles and how they can be used to go on the offensive. They need Roz and Dorcas back before their transformation to stone becomes irreversible. As it stands, the pagans don’t know about the hedge witches, and Sabrina wants to use that to her advantage.
Lucifer, still trapped in Faustus Blackwood’s body, poses as a Christian priest to gain access to Mary Wardwell’s home in search of Lilith. He claims that he’s visiting the homes of good Christian folks to warn them that evil is afoot. The Devil has come to Greendale. Mary admits to having felt his presence and the fact there's so many things she has no explanation for. He tells Mary that Satan has allies in the form of witches, such as Sabrina Spellman and her family. He informs Mary that they seek to destroy her and make her unholy. He tells Mary how the Devil can disguise himself as loved ones. Hearing this, Mary begins to suspect that Adam is actually the Devil. Lucifer asks for Mary’s permission to confront him, which she gives. Lucifer goes in the back and finds Lilith, he then forces her to reveal herself to Mary, who runs out the door in shock.
Hilda calls Zelda and tells her that she killed Dr. Cerberus. She asks Zelda to bring a gun to Cerberus Books.
Sabrina and Ambrose get the hedge witches drunk off vino. As Gryla, Pesta, Sycorax, Dezmelda, Mother Hubbard, and Mambo Marie drink, and with their inhibitions low, Sabrina persuades them into taking the fight to the pagans. As Sabrina goes to the carnival to confront the pagans, Ambrose and Prudence stay behind at the Academy with the hedge witches as they channel each other, as well as the stones for power to lend to Sabrina.
With Salem at her side, Sabrina enters the carnival. She uses the powers of Petsa, Sycorax, and Gryla to take out the approaching pagans. Salem then distracts Circe long enough for Sabrina to grab her and teleport her back to the Academy, where she is bound in chains and held at gunpoint by Sabrina, Harvey, Ambrose, Prudence, Theo, and Robin. Sabrina demands that she return Roz and Dorcas back to flesh. If she refuses, they’ll just cut off her hands. Circe submits and turns Roz and Dorcas back to flesh. Prudence embraces Dorcas. The Same goes for Harvey with Roz. Robin then tells Circe to turn Billy, Carl, Martin, and Eric back into humans. Circe informs Robin that Pan and Nagaina will kill him for betraying them. As the boys are turned back into humans, Prudence compels them and leads them out of the Academy.
Zelda arrives at Cerberus Books with a shotgun in hand. She finds the shop covered in spiderwebs. Zelda slowly approaches Hilda from the darkness. Hilda reveals that the pagans turned her into a spider-woman and that is why Zelda has to shoot her. Zelda points her gun at Hilda and fires.
At the Academy, Prudence informs Ambrose, Dorcas, Theo, Robin, Roz, Harvey, and Sabrina that the Circe is in the dungeon and the boys are back home, none the wiser. Harvey welcomes Robin into the Fright Club and tells Roz that she’ll never lose him.
Sabrina runs into Nick, who apologizes for his earlier remarks. He asks if they’re still friends, and she nods her head yes.
At Prudence and Ambrose’s behest, Mambo Marie teaches Judas and Judith the way of Hatian Vodou, such as how a mèt-tèt is a guardian spirit that watches over them from the moment they are born. They each have one, as everyone is worthy of its guidance. Prudence and Ambrose look on from the edge of the room, where Prudence admits that while she may have invited Mambo Marie, she came for her own reasons. Until they’re revealed, Prudence wants her to teach them her ways.
Lucifer sits in a bathtub as Lilith pours water over his body in preparation for the separation ritual from Blackwood. She puts Lucifer to sleep and wakes up Faustus, allowing him to gain control of his body for the first time. Now that Lucifer is asleep, they have business to discuss. They must both perform an act to ensure they both remain alive after Lilith separates him from the Dark Lord.
Zelda buries Hilda’s body in the cemetery. Unbeknownst to her, Mary Wardwell watches from the nearby woods. Afterward, she returns inside, where she, Sabrina, and Ambrose discuss how Hilda killed Dr. Cerberus and how if Hilda told them the truth about her metamorphosis, they could’ve simply had Circe revert her back rather than Zelda having to kill her and bury her in the Cain Pit. It’s for that reason, Zelda demands they start talking as a family again. If Zelda’s hunch is correct, Hilda should rise from the pit as her normal self. Lastly, Zelda tells Sabrina and Ambrose that they’ll dine as a family and return to the Academy with Hilda to combat the pagans once she rises.
Sabrina takes Prudence’s advice and performs a cord-cutting spell to remove any emotional ties to Nick. Salem warns her against it, but Sabrina feels that she must. He asks what of her feelings for Harvey. Sabrina will always love Harvey, but she doesn’t think she’s in love with him anymore. However, better to be safe than sorry, so Sabrina writes Harvey’s name on the candle alongside Nick’s, cutting any emotional ties to him too, as she lights the candle.
While waiting in the parlor for Hilda to resurrect, Zelda hears a knock at the door. She answers. Mary Wardwell pulls a gun from her jacket and shoots Zelda in the chest, stating that "this is for Adam."
