Percy Rogeen's father fears his son will never be a man, but only a mama's boy. When a friend of Mr. Rogeen promises to help the boy shape up, the father is delighted. But the help comes in the shape of a bottle, and Percy finds himself drunk aboard a freight car bound for the middle of nowhere. In a border town, Percy gets a job on a plantation and makes a name for himself playing the violin in a cantina. By the time his father arrives to rescue him, Percy is no longer the timid cry-baby of before, but the tough rescuer of the local farmers' land.
