When Walter, a bathrobe-clad octogenarian, robs the bank using a concealed banana as the hold-up weapon, Kate and Aunt Kitty speed after him in Kitty's mammoth 1974 Eldorado convertible. But instead of retrieving their cold hard cash, they find a still-warm dead body, much to the consternation of a certain sexy sheriff who happens to be Kate's person of interest in the boyfriend department. Things go from bad to worse when Kate's ex-flame from the Treasury Department and a quart-low biker gang - the Devil's Cheerleaders - get involved in the mayhem. Despite continuous misadventures - from Sausage Festival pandemonium to a malfunctioning giant man-eating plant from Splotski's Theatre Rentals - Kate and Kitty are determined that the show must go on.
