Back in Texas he might be The Rio Kid, but at the other end of a long cattle drive in Fort Collins, Rio Bell is now struggling through his first year as a Colorado rancher. With his new wife, old hands, and a few mountain men, he's learning fast as they deal with winter weather and stubborn cattle. The killing cold and deep snows bring all new challenges to calving and just getting in supplies, but tempers can run hot as ever. Not everybody wants to see him succeed... or even survive. They're about to learn he's no greenhorn when it comes to taking care of business, regardless of what that particular business may be.
