Fleeing the police after a bank robbery that went wrong, a group of offenders decides to take refuge on a deserted island. The apparent tranquility of this place actually hides a horde of demonic creatures desperate to satisfy their cannibalism and carry out their mission: to impregnate women with the seed of the devil, and enslave men. One after the other the criminals will be hunted down, abused, murdered; and this island, meant to be a peaceful refuge, will become their tomb.
