Charlie Dawson and his partner Clem made a bad error in judgment on a gold mine deal and ended up in a shootout with some very angry claim jumpers. The unlucky pair hightail it to San Francisco, where they try to blend into the notorious red-light district known as the Barbary Coast. A big boss banker wants to hire them to find a crate that was lost in a train derailment. Inside is the priceless golden spike created for the opening ceremony of a new rail line. Sounds like easy money. Problem is, a vicious gang of outlaws are on a direct collision course with the hard-to-kill duo. And they're all heading for one very dead end.
