"Tonto" Daily fails as a cowpuncher for Weston, wealthy cattleman, and is demoted to chuck-wagon driver. He falls even lower, in Weston's estimation, when he loses the wagon in a river crossing and imperils the life of Nina, Weston's daughter. Porky and Tex, two worthless cowboys, who aspire to own a pig farm, learn that Daily has inherited a fortune and they beg him to invest in their pig-farm venture. Daily declines. In spite of his bumbling mistakes, Munther, the ranch foreman, and a rustler on the side, keeps Daily around. He assigns him to guard 5,000 longhorn cattle in the Weston stockyards. When he falls asleep, Munther and Joe Gilbert, a suitor for Nina's hand, steal six hundred head of cattle and hide them in a cavern below the Mexico border. Daily flees the situation and invests money in the pig farm, but his heart is still with the cows.
