Colorado, 1868. A stagecoach is ambushed by a gang that cold-bloodedly murders the driver and all the passengers. Only a young girl, Eleanor, survives the massacre. In Ogden, mine owner Mullins wants to send a team to take down the gang. He tasks Marshal Sharp with recruiting men for the job. Sharp knows that only one person can lead this mission to success - Duke. However, Duke initially refuses. It is only when he learns that Mullins is hiding a secret that he agrees. Mullins reveals to Duke that he is supposed to send $100,000 by stagecoach to a consortium in California, of which he is a member. Duke offers to oversee the transport for a share of $10,000. However, Mullins only agrees to this deal on the condition that Duke joins Sharp's team. And so the team, led by Sharp and Duke, sets out on their journey.
