Trailer-dwelling, sewage-pumping Chip may not lead the most glamorous life, but he's got one thing going for him: he's head over heels infatuated with his girlfriend Liza. He's more than willing to overlook her wild streak, the fact that she's hooking up with their landlord, and her rather extreme mood swings, so when she proposes a plot to steal $68,000, he goes along with the plan.
