Morituris: Legions of the Dead

While out driving, three young men meet two beautiful women and convince them to go with them to a rave out in a remote location. Once there, the women realize that there is no rave and that the men lied to them in order to beat and rape them. The women try to escape, only to accidentally unleash a pack of zombie gladiators that proceed to attack the group as a whole. (Synapse Films)
