A group of young people travel by boat to a small island in the Aegean Sea for a carefree holiday, but their enthusiasm soon ebbs with the discovery of a horribly mutilated body. They would leave the island, but their boat has mysteriously slipped its moorings and drifted away, leaving them stranded.
They pass the night in a small house, where one of their party is seriously wounded by a terrified blind girl hiding in the basement. They finally discover the island's grisly secret in the pages of a diary: a derangered inhabitant of the island has developed an appetite for human flesh and is lurking in the shadows, waiting to have them for dinner!
The youngsters must battle for survival against this blood-thirsty cannibal!
