Endlings (2012)

Four strangers awaken in a dank room. Not knowing how they arrived or when they will be able to leave, they quickly form alliances, each playing the other for supremacy. However, their efforts prove useless in the face of a charming, all-knowing adversary. Viciously funny and destructively unapologetic, Endlings is a viciously sharp thriller that examines the question "What do you really know"?
