Marla Briones is living a perfect life with her boyfriend by her side and her reputation as the top student in her batch. However, her world begins to crumble when compromising photos of her and three other girls are leaked across the campus.

Marla accuses their boyfriends of leaking their nude photos, only for their school to turn a deaf ear and impose unfair punishment on the girls. As they plot their own form of justice together, Marla considers seeking help from an unlikely person.

Upon confirming the boys' involvement in their embarrassing plight, Marla and her friends execute an elaborate eye-for-an-eye plan. However, the backlash exposes how gender bias and power truly operate inside SOSH.

Much to Nyx's disbelief, the girls uncover Ant's dirty little secret and seize the opportunity to confront him. However, tension rises when Isobel disagrees with their plan.

With their whole revenge scheme on the brink of collapse, Isobel smooths things over and opens up to Nyx. But as the girls set their sights on their next target, things take an unexpected turn.

April's objection to the girls' proposed next target leads to the discovery of her dark secret. But when Marla confronts her over her betrayal, she is left with no choice but to leave the group.

The girls' effort against their predatory teacher pays off. However, Marla and Daphne's attempt to fix their toxic relationships threatens to destroy the group.

When Marla decides to give Cole another chance, Isobel, Nyx, and April think of a way to bring him down. Soon, they take advantage of SOSH's event to bring the truth to light.

With Ant back at SOSH, Cole and the boys wage war against the girls. Threatened by the boys' malicious blackmail, Marla's group is forced to make a heartbreaking sacrifice at the science fair.

Marla's compromising video still gets leaked, forcing Warren to confront Cole. Fed up with SOSH's systemic injustice and their abusers, the girls execute their final act of revenge during prom night.
