Joe D'Amato co-writes and directs this controversial Italian horror. A group of young tourists venturing to a remote Greek island become the victims of a murderous, cannibalistic creature.

When they head to a mansion on the island they unearth some clues about their stalker's identity. But this is only the start of their horror...
