Split (15)

For her birthday celebration at a local restaurant, popular high school student Claire Benoit invites her classmates, including best friend Marcia and creepy outcast, Casey. On the way home, a socially awkward misfit called Kevin Crumb overpowers Claire's father and kidnaps the three girls, spiriting them away to a bunker. The teenagers woozily regain consciousness from chloroform fumes in a cell without windows or obvious means of escape, completely at the mercy of their captor.
