Set at Preston University, Cruel Intentions 3 follows Cassidy Merteuil, a distant relative of the original film’s Kathryn Merteuil. She meets two charming but twisted young men — Jason and Patrick — who engage in a dangerous game of seduction and manipulation, using their classmates as pawns.

Cassidy, however, isn’t a simple target. She plays the game just as ruthlessly as the boys — perhaps even better. As romantic rivalries escalate, each player in this psychological game becomes a threat to the others, leading to a dark climax where secrets unravel and reputations are destroyed.
