Young rapscallion Penrod Schofield causes a good deal of trouble in his community, all in the name of protecting kids from too-strict parents and nasty neighbors. He heads the ABPA (American Boys' Protective Association) and through it disrupts a number of local social events. The townspeople are pretty fed up with Penrod and his gang, but when a couple of outlaws come to town, Penrod shows his mettle.
