For Willie's birthday, Jase organizes a family trip to Lake D'Arbonne, a favorite hangout of the brothers in their youth. The outing gets off to a rough start, with Jase haggling to rent a boat, no one being able to find the key to the lake house, and Phil recruiting Miss Kay and his granddaughters to catch a raccoon running loose in the house. Jase's attempts to draw Willie into fun activities fall flat until he and Jep spot a man using a water-powered jet pack and set up a chance for Willie to use it as his last and best birthday present.
