Plot summary
After helping Jerry out with numerous tasks, Earl has discovered that his prison term has been reduced to six months and ten days left in jail. Jerry offers to remove six months if Earl can help launch a program that works between the inmate and the victim or victim's family. Earl chooses an inmate whose meth lab had exploded and had burned his parents' house down. The inmate agrees to participate if Earl would throw a prison prom, because he missed his in high school. Earl turns to Joy to help plan the prom, and soon discovers it will cost him the rest of the money he had left from his lottery winnings.
Knowing that paying for the prom will earn him his freedom, Earl agrees to give up the rest of his money and the night is a success. But the inmate reneges on the deal and refuses to reconcile with his parents, leading Earl to settle things in a more direct style.
