Lance Gordon killed his father's murderer in a fair fight, but now he's got a price on his head and has been running from the law ever since. Cornered by men of the US Cavalry in Santos, Lance gets rescued by a mystery man who convinces him to join forces and go after a notorious cattle rustler up the infamous Coyote River. Even together the pair stands barely a chance of bringing the gang thieves to account, much less dealing with the soldiers still hot on their trail.
