Bad Sister is a psychological thriller that centers on Zoe, a teenage girl who becomes suspicious of a new nun, Sister Sophia, at her Catholic school. At first, Sister Sophia appears kind, youthful, and charismatic—quickly earning the admiration of students and faculty alike. However, Zoe soon notices strange and unsettling behavior, especially Sister Sophia’s growing obsession with Zoe’s older brother, Jason.

As Zoe digs deeper, she discovers that Sister Sophia is not who she claims to be. In fact, she is a dangerous impostor with a dark past, using her false identity to get close to Jason and eliminate anyone who stands in her way—including Zoe. Despite Zoe's warnings, no one believes her at first, thinking she’s overreacting or jealous.

The tension escalates as Sister Sophia’s manipulative and violent tendencies grow more extreme. Zoe must fight to protect her brother and uncover the truth before it’s too late. The film builds suspense through mistrust, hidden motives, and the increasingly twisted actions of the antagonist.

In the end, Bad Sister delivers a cautionary tale about appearances being deceiving, and the dangers that can arise when evil hides behind a mask of innocence and faith.
