In this horror film by director Tomas Aznar, a group of teens go on a vicious killing spree. First a young teen stabs a businessman to death, then she and three friends head out to a diner and kill everyone except for one couple. The couple is only spared because they are taken hostage. So far, the motivation for the gory, inhuman slaughter is money; both the businessman and the diner are robbed. Next, the group go into a home and after stealing more money, they burn the house down, killing an old woman and a child. But when the cold-blooded killers take refuge in an old, deserted monastery, the spirits of the dead, the murdered, and who knows what else come out looking for revenge.
