With jobs hard to come by after the war, Slocum jumps at the chance to wrangle wild cattle-and get some food in his belly. He's in good company with another cowboy, the one eyed Mexican Paco, and a beautiful escaped Comanche captive, Mary Van Housen.
In the midst of herding the critters and protecting Mary from her former captors, Slocum and Paco lose the rest of their camp to a disgruntled ex-employee. Continuing towards Missouri to see the job through, they're trailed by enemies who want the entire herd of them dead. Looks like Slocum's got a few more wild animals to yoke...
