SEEKEST THOU THE ROAD
Three years after her defeat by Wanda Maximoff in Westview, New Jersey, the witch Agatha Harkness is trapped under Wanda's spell, believing herself to be the police detective Agnes O'Connor within a crime noir television series titled Agnes of Westview, where she is fixated on a Jane Doe murder case. One night, a teenager breaks into Agnes' house, looking for "The Road". Agnes believes he is tied to the murder case and arrests him. Rio Vidal, an FBI agent, comes to Agnes and helps her remember her true identity and realize the Jane Doe she is seeing is actually Wanda's body. Waking up from the spell, Agatha realizes that her powers are gone and that Rio, a fellow witch with whom Agatha has history, is there to kill her. Agatha convinces Rio to spare her until she gets her powers back, but Rio warns Agatha that the Salem Seven will soon come after her. After Rio leaves, Agatha is unsure what to do about the "Teen", whom she actually kidnapped under the influence of Wanda's spell.
CIRCLE SEWN WITH FATE / UNLOCK THY HIDDEN GATE
Teen reveals he freed Agatha from the spell and wishes to travel the Witches' Road, which rewards any witch who survives its trials what they desire most in Agatha's case, the restoration of her powers. Agatha also realizes magic is preventing her from learning any personal information about Teen, including his name. Needing a coven to open a portal to the Road, the pair recruits the witches Lilia Calderu, Jennifer "Jen" Kale, and Alice Wu-Gulliver who all have reasons to walk the Road as well. Needing a "green witch" but not wanting to recruit Rio, Agatha instead turns to Westview resident Sharon Davis, a talented gardener. As the four witches and Sharon perform the ritual to open the gate to the Road, they and Teen escape through it to narrowly evade the Salem Seven. The group then removes their footwear and sets off on the Witches' Road.
THROUGH MANY MILES / OF TRICKS AND TRIALS
Agatha explains that to reach the end of the Road, the coven will face trials focused on different branches of witchcraft. They also realize that Teen's sigil prevents any witch from learning his identity. At the first trial, the coven finds a coastal house with a bottle of wine that everyone but Teen drinks. Jen privately warns Teen not to trust Agatha, who is said to have traded her child for the Darkhold. A timer starts counting down, and Jen realizes the wine was poisoned as Sharon faints. As they gather ingredients to create an antidote, the witches hallucinate: Lilia sees her younger self and her maestra from the Renaissance era, Jen hallucinates a doctor forcing her underwater, Alice sees her mother Lorna Wu about to commit suicide, and Agatha sees a crib containing the Darkhold. As they prepare the antidote, the house is brought underwater, threatening to drown them. With a few seconds left, they finish the antidote, drink it, and feed it to Sharon. Water pours in, but a tunnel appears in the oven and the coven escapes through it back to the Road. As they recover, Teen discovers that Sharon is dead.
IF I CAN'T REACH YOU / LET MY SONG TEACH YOU
After burying Sharon, the coven is forced to summon a replacement green witch. Rio emerges from Sharon's grave, much to Agatha's annoyance. The coven encounter a house with a 1970s aesthetic that prompts renewed feelings of grief for Alice as it turns out to be a recording studio tied to Lorna. Just as Rio playfully suggests to Agatha that they betray the others, which is overheard by everyone, Teen accidentally plays a record backward, summoning the demon who is the source of the curse in Alice's family. To fight it, the group plays Lorna's version of the Ballad, revealed to be a protection spell, and Alice is able to kill the demon. As the coven leaves the house, they notice Teen had been severely wounded during the trial. Back on the Road, Jen is able to heal his wound, saving his life. Later on, Lilia, Alice, and Jen bond while Rio alludes to her history with Agatha. Teen asks Agatha what happened to her son, but she does not answer. Later, as Agatha tries to kiss Rio, she tells Agatha that Teen is not her son.
DARKEST HOUR / WAKE THY POWER
The Salem Seven chase the coven, who evades them using makeshift flying broomsticks. After being pulled back down by the Road, they enter the next trial which takes the form of a cabin with a 1980s aesthetic. The group uses an Ouija board and makes contact with Agatha's mother Evanora, who was killed by her daughter in 1693 along with her previous coven, revealed to be mothers of the Seven. Warning the coven to leave Agatha behind, Evanora possesses her and attacks the group. Alice uses her powers to expel Evanora from Agatha, who proceeds to absorb Alice's magic. Teen, noticing another spirit's presence, stops Agatha by shouting its name: Agatha's son Nicholas Scratch, but Alice dies. Agatha insists that it was accidental, but Teen lashes out at her as well as Lilia and Jen, who affirm that their goals are the same as Agatha's. The latter mocks Teen by stating that he is just like his mother; angered, he magically forces Lilia and Jen to toss Agatha into a mud trap, then blasts them in as well. As the witches sink, a headwear similar to the Scarlet Witch's appears on Teen's head.
FAMILIAR BY THY SIDE
In flashbacks, William Kaplan, a teenager from Eastview, is celebrating his Bar Mitzvah where he encounters Lilia. Reading on his palm something she does not disclose, Lilia casts the sigil on William to protect him, instantly forgetting his identity. The party ends when the Hex created by Wanda begins to fall. While driving past Westview, William and his parents get into a car accident and he dies, but at that moment, Billy Maximoff's soul enters William's body, resurrecting him. William struggles to adjust after the accident due to his newfound ability to read minds and his lack of memory of his life before. Three years later, William and his boyfriend Eddie meet with Ralph Bohner, who used to be controlled by Agatha inside the Hex. He tells them about what happened there and about Wanda's twins Billy and Tommy, making William realize he is actually the former. Determined to use the Witches' Road to find Tommy, whom he can still sense, Billy goes to Agatha and breaks Wanda's spell. In the present, Agatha escapes the mud and, realizing the sigil has been destroyed, deduces Billy's goal and tells him that they must continue together since he cannot control his power.
DEATH'S HAND IN MINE
Agatha and Billy continue on the Road before coming across a castle. Upon entering, the two are garbed as the Wicked Witch of the West and Maleficent, respectively, and are presented with tarot cards. If they do not place the proper cards in the correct sequence, swords hanging from the ceiling fall down. Flashbacks from Lilia's childhood lesson in divination reveal that she has been experiencing her life out of order, explaining her memory lapses. After falling through the mud, Lilia discovers that Rio is the personification of Death (something Agatha knew), who forebodes that her time is coming. She awakens Jen, and after evading the Salem Seven, they venture through the tunnels before reuniting with Agatha and Billy (Lilia is dressed as Glinda, Jen as the hag version of the Evil Queen). Knowing the trial is hers, Lilia places the cards in their proper order, saving them all. Prompting everyone to flee through the exit, Lilia chooses to stay behind as the Salem Seven approach. She flips one of the cards, causing the entire room to flip, impaling most of the Seven and presumably herself. In the last scene, young Lilia gleefully attends her first lesson in divination.
