Broncho Billy becomes engaged to Mae, whose sister, Marguerite, is a cripple. Her parents are unable to stand the expense of an operation which will cure her, so she starts in to save the necessary $100. Slowly the money accumulates. Meanwhile Broncho Billy is caught making moonshine whiskey in Gulch Canyon. Mae turns against him instead of sympathizing and returns his ring. By this time Marguerite has saved $100 and is about to mail the letter asking the doctor to come when she learns that the government will release captured moonshiners upon payment of $100. She tears up the letter, then takes the money she worked so hard to save and turns it over to the authorities. That evening finds Broncho asking Marguerite to become his wife, while her sister becomes engaged to another man.
