From director Gaspar Noe (ENTER THE VOID) and actress Sofia Boutella (ATOMIC BLONDE) comes this hypnotic, shock-filled story of a party that descends into delirium over the course of one wintry night. In an empty and remote school building, a French dance troupe has gathered for rehearsal. The rehearsal morphs into a party and then turns nightmarish as the dancers discover they've been drinking sangria laced with LSD. Passions and violence erupt as the night moves from jubilation to full-fledged anarchy.
