Six wayward teenagers who'd run into trouble with the law, and their court-appointed guardians, Sara and Martin Randhurst plan to camp for three nights on a small island off of Michigan's upper peninsula. Then Martin told a campfire story about the island's history. Of the old civil war prison hidden in there, and the starving confederate soldiers who resorted to cannibalism to stay alive. Everyone thought it was funny. They even laughed when Martin pretended to be dragged off into the woods. But Martin didn't come back. And neither did Sara when she went in search of him.
