Climax

Climax is a movie starring Sofia Boutella, Romain Guillermic, and Souheila Yacoub. French dancers gather in a remote, empty school building to rehearse on a wintry night. The all-night celebration morphs into a hallucinatory...
When a dance troupe is lured to an empty school, a bowl of drug-laced sangria causes their jubilant rehearsal to descend into a dark and explosive nightmare as they try to survive the night—and find who's responsible—before it's too late.
