On a Mars colony in the year 2145, an officer in a rebel militia discovers that his sister, who was abducted a dozen years before, is still alive and has been raised as a soldier whose goal is to bring about the destruction of her brother's faction.

Lewis Hicks (Cuba Gooding Jr.) is a reporter and journalist specializing in writing about the crime of murder. Instead of writing his next story, Lewis becomes the story when his new girlfriend is sadistically murdered, and he is the only suspect. Lewis investigates the murder himself and finds the killer's journal with his past victims and a death list of his future prey. Lewis believes that he is the only person who can stop the killer before time runs out for his next victim.
