However, his new job is not as he expected, and he realizes that no one else on the island would work for his sadistic employer. He soon learns that Mile Marker Zero is indeed the end of the line and there is nowhere else for him to run. And he begins to suspect that his boss is hiding a damning secret. Planning to uncover the mystery and use it as a weapon against the cruel, self-important man, Christopher's quest leads him into the underground of the Florida Keys. There he finds hustlers, drag queens, and victims of the sex trade, who all seem to hold a piece to the puzzle. Meanwhile the body count is rising.
