The Simpson family attends a prison rodeo where Marge meets Jack Crowley, a convict whom she believes to have great artistic potential after becoming impressed with his work. She later teaches a class on being an artist to the prisoners and befriends Jack. With Marge's help, Jack is granted parole under her custody. Marge soon finds a mural-painting job at Springfield Elementary School for him. Jack paints a powerful mural symbolizing school spirit with a warrior woman riding a puma, which the whole school likes, but Principal Skinner demands he tone it down using his idea of a cartoonish puma walking with two children under a rainbow in a fantasy land. Jack reluctantly gives in to his wishes; however, upon its unveiling, the new mural is panned by everyone in town. Refusing to admit that he forced Jack to create it in the first place, Skinner instead blames Jack and fires him.
