Teenager Maggie Thompson relocates to her hometown in Ohio with her mother, Erica, after they face a significant change in their family dynamic due to her father leaving. This move marks the beginning of a new chapter for Maggie as she tries to adjust to her life away from her previous home.

As Maggie begins her new life at school, she quickly bonds with a group of peers which includes Haley, Darrell, Chaz, and Andy. This newfound camaraderie helps her navigate the challenges of being the new girl and offers a sense of belonging.

In search of fun, Maggie and her friends persuade Sue Ann 'Ma' Ellington, a veterinary technician, to procure alcohol for their party. Unfortunately, their excitement is short-lived as Sue Ann betrays them by alerting the authorities about their activities.

Miraculously, the group is let go after an officer recognizes them, owing to past dealings with Andy’s father, Ben. The close call leaves Maggie and her friends relieved but wary of Sue Ann's intentions.

The next day, Sue Ann hosts the group at her home, having transformed her basement into a vibrant party space. This gesture wins her popularity among the students, and she revels in the newfound attention.

Sue Ann becomes increasingly overbearing as she pushes for inclusion in the group's activities. Her jealousy overspills one evening when she observes a tender moment between Maggie and Andy, leading her to commit a shocking betrayal.

Maggie awakens disoriented, missing her earrings and bearing bruises, realizing she has been drugged by Sue Ann. Distressed, she confides in Andy about her intent to stay away from Sue Ann, who is becoming a dangerous presence in their lives.

To regain the trust of the group, Sue Ann fabricates a story about having pancreatic cancer, attempting to explain her erratic behavior. However, this deceit is soon jeopardized when Haley notices a friend’s bracelet on Sue Ann, raising suspicions.

Determined to uncover the truth about Sue Ann, Maggie and her friends decide to investigate her home. Their encounter with Genie, Sue Ann's able-bodied daughter, brings shocking revelations and leads to their narrow escape just before Sue Ann returns.

Ben makes an unplanned visit to Sue Ann's workplace, where he confronts her about the repeated visits from Andy. During this tense exchange, Ben's previous betrayal of Sue Ann is revealed, adding layers to their complex relationship.

As Sue Ann descends further into madness, her actions grow increasingly violent, culminating in the running over of Mercedes and the shocking murder of her boss. These acts reveal her troubled psyche and set the stage for her escalating brutality.

Maggie's worst fears come to life as she discovers her friends are chained in Sue Ann's basement, victimized by her delusions. This horrific scene highlights Sue Ann’s twisted belief that she alone deserves to belong to their social circle, escalating the tension.

Just when it seems all hope is lost, a rescue attempt is initiated. Chaos ensues as Sue Ann's house goes up in flames while Maggie fights desperately to save her friends, demonstrating her courage amidst the horror.

In a shocking climax, Sue Ann succumbs to her insanity, finding herself in bed with Ben's corpse even as the flames rage around her. This grotesque moment symbolizes the culmination of her twisted fantasies, marking her ultimate downfall.
