Joan Mitchell, a 39-year-old wife living in a quiet Pittsburgh suburb, feels trapped by her role of a housewife despite her husband Jack’s success as a businessman. Their home is filled with tension: Jack is often busy, domineering, and occasionally violent, jetting off on week-long business trips that lengthen the distance between them. Joan attends psychotherapy to make sense of recurring dreams where her husband asserts control and even muses about “kicking some ass.” The fear and pressure crescendo when a confrontation ends with Jack striking Joan in the face, leaving her unsettled and wary.
Joan’s world starts to tilt further when she and her friend Shirley hear about a mysterious new neighbor, Marion Hamilton, who is rumored to practice witchcraft. Curious and hungry for meaning, the two women visit Marion’s home for a Tarot reading, only to discover that Marion is not merely a rumor but the leader of a local witches’ coven. The encounter hints at a hidden world that promises agency and power, a door that Joan feels might finally open.
Upon returning home, Joan and Shirley run into Nikki, Joan’s 19-year-old daughter who attends college and is openly navigating a casual relationship with Gregg, a student teacher at Nikki’s college. The four adults share drinks and conversation, and Gregg shows an unmistakable interest in Joan. She rebuffs him, yet tensions flare when Joan ejects Gregg after he cruelly deceives Shirley into believing she has smoked pot. The evening takes a charged turn when Joan, after dropping Shirley off, discovers Nikki and Gregg in a private moment—Nikki and Gregg are having sex. A mixture of arousal and guilt surfaces as Joan quietly returns to her room and begins to touch herself, only to be interrupted by Nikki.
The morning after, Nikki disappears without a word, and Jack heads out on another week-long trip. Joan, feeling increasingly lonely, absorbs herself in a growing curiosity about witchcraft. She buys a book on the subject and secretly begins experimenting, conjuring a spell to draw Gregg closer to her. Soon they embark on an affair, and Joan’s life becomes a tapestry of rituals, tattered dreams, and an escalating sense of danger. Her nightmares grow more vivid, featuring an intruder wearing a Satanic mask who seems poised to break into her life. Through late-night spells and research, Joan’s reality begins to fray at the edges while she explores the seductive pull of the coven’s world.
Meanwhile, law and order intrude as Nikki is located in Buffalo, New York, and is expected to return home in three or four days. After one final sexual encounter with Gregg, Joan tells him she does not wish to continue their affair, signaling a shift even as the fascination with magic intensifies.
A climactic night returns, and another terrifying nightmare pushes Joan to the brink. She shoots and kills Jack when he unexpectedly comes home early, leaving the act shrouded in ambiguity—whether it was an accident or a deliberate act remains unrevealed. In the aftermath, Joan is initiated into Marion’s coven through an elaborate, almost theatrical ritual that seals her new identity. The incident around Jack’s death is ruled an accident, clearing Joan’s name in the eyes of the law, and a celebratory party afterwards becomes a stage for revelation. A compliment on her youth and beauty prompts Joan to reveal her true allegiance, and she greets the room with a wry smile as the guests refer to her as “Mrs. Mitchell” or simply “Jack’s wife,” marking a sharp turn from the life she once led and signaling the sisterhood she has joined. In this new frame, her appearance and status take on a different, provocative meaning within the neighborhood and the world she has chosen to inhabit.
