Overview:The Cartwrights are about to start a major cattle drive with other ranchers. It has been decided that Ben's foreman will be trail boss on the drive. Weatherby, a fellow rancher who is also with Ben, has agreed to have Kelly as trail boss, until he finds out that Kelly was previously on a cattle drive with him, and fired him for drinking. Weatherby also suggests that his younger wrangler take the job as trail boss, and a conflict is started between both Ben's foreman and Weatherby's wrangler.
