Conger is in jail and given an opportunity to get out on one condition: he must go back in time and kill a man whose impact changed the world for centuries to come. He receives a skull, which he can use to identify the man when he gets to a different time. Yet upon arriving, he soon discovers that the task will have far more serious consequences than he had ever imagined.
