In the intriguing beginning, three teenage girls—Frankie, Tabby, and Lourdes—attempt to manipulate time through magic, but their efforts are in vain as they need a fourth member to complete their spell. Enter Lily Schechner, who moves to town with her therapist mother, Helen, to start a new life alongside Helen's husband, Adam Harrison, and his three sons, Jacob, Isaiah, and Abe. While the boys act awkwardly around Lily, she grapples with feelings of isolation.
On her first day at a new high school, Lily's luck begins to change. After an embarrassing incident related to her period, she finds unexpected friendship among the three girls. They generously offer her a pair of shorts when she becomes the target of ridicule, especially from Timmy Andrews. Their bond strengthens when Lily showcases her latent telekinetic powers, inadvertently pushing Timmy into lockers. As punishment, both she and Timmy find themselves in detention, but Lily manages to escape using her mind, leading her to meet the girls outside. Recognizing her potential, they invite her to join their coven, which Lily eagerly accepts. This marks the beginning of their adventures as they successfully freeze time during their first magical attempt.
As their friendship blossoms, the girls seek retribution against Timmy by casting a spell involving a personal item they discover in his home. Their incantation leads to a softened demeanor from Timmy, a testament to their newfound powers. The group delves deeper into their magical abilities, experiencing feats like levitation. However, when Adam learns about the incident and reprimands Lily, a conflict with Helen ensues, revealing tensions beneath the surface. In a moment of vulnerability, Abe shares his thoughts on their father's strict beliefs.
Amidst this growing tension, Timmy's overtures of friendship unfold at a party, where he unexpectedly admits his bisexuality, having been intimate with Jacob's brother, Isaiah. In a whirlwind of emotions, Lily, under a spell's influence, shares a romantic kiss with Timmy. Yet, everything takes a dark turn the following day when their teacher informs the coven that Timmy has allegedly taken his own life. Confronted by this tragedy, Lily confesses her love spell to her friends, prompting them to distance themselves from her and relinquish their magical practices.
Feeling uncertain about Adam, Lily urges her mother to relocate, but Helen maintains her stance. In a determined effort to uncover the truth, Lily explores Adam's office, where she stumbles upon her adoption papers and learns a shocking fact: she is the child of Helen's former patient. The burden of this revelation weighs heavily on her during Timmy's funeral, which serves as a catalyst for Helen to finally agree to move.
In a shocking twist, it is revealed that she is aware of Lily’s magical gifts and wishes to take them for herself. When Lily grows suspicious, Adam, now revealed to be a deceptive figure, threatens her life, seeking to inherit her Wicca powers due to his affiliation with a sinister pagan cult. During a chilling confrontation in the woods, he confesses to the murder of Timmy and demands Lily's powers under threat of death.
However, a connection with her friends is not severed; through a Ouija board, Timmy reaches out, urging the girls to save her. They rally, freeze time, and attempt to overpower Adam, but he quickly turns the tables. In a climactic showdown, the girls band together, wielding their elemental magic to defeat Adam, ultimately leading to his fiery demise.
In the aftermath, Lily reestablishes her bonds with the girls, deciding to bind their powers with the hope of mastering them. The story concludes as Helen escorts Lily to a nearby clinic, paving the way for an emotional reunion with her biological mother—revealed to be none other than Nancy Downs, a character of intrigue and legacy. Lily's journey unfolds a tapestry of friendship, magic, and a search for identity, leaving viewers captivated and yearning for more.
