When a game goes wrong, the formidable Dr. Scharff catches Mitch, Lenny, and Aaron accidently damaging her property. The bill is huge, and Dr. Scharff promises to call the boys parents -- unless they pay her by Friday. The debtors decide to pool their limited talents in a wacky jazz combo. But their get-rich0quick scheme backfires until Leroi Rupert, their favorite disc jockey, decides to even up his own score with Dr. Scharff.
