During the winter in the 1990s, a group of 20 French dancers meet for a three-day rehearsal in a remote abandoned building. At a party to kick off their gathering, they all unknowingly consume sangria that has been laced with LSD. Soon, their celebration becomes an all-night nightmare in which the drugs unlock their fears, anger, neurosis and more, turning the gathering violent. Written and directed by Gaspar No?. Sofia Boutella co-stars.
