The sole survivor of a devastating shipwreck finds himself in the middle of nowhere surrounded by endless water. The island looks like a piece of the Heavens, but he's the only human being on it; besides, food and water are of the essence, which means he'll have to find a way to go back to civilization. Eventually, he creates a raft and learns how to navigate through the dangerous waters. However, there is a red turtle out there that doesn't want him to leave. Every time the man thinks the island is done with and he's going home, the creature takes him back. Why won't it let the poor human escape? Is it an evil spirit, a demon sent to stop him, or maybe there's more to it than meets his exhausted eye?
