Owing his life to washed-up pugilist Leon Platt (Denny Miller), T.C. (Roger E. Mosley) enters a bare-knuckle boxing match, intending to use the prize money to save Leon and his daughter Ima (a pre-Beverly Hills 90210 Shannen Doherty) from being tossed into the street. Figuring that T.C. hasn't got a chance, Higgins summons aid from Magnum--who happens to be several thousand miles away on assignment in his home town of Detroit. Even so, Magnum is able to save the day with the eleventh-hour assistance of two celebrity benefactors. And wait until you see what sweet little Ima Platt does to Higgins' prize dobermans Zeus and Apollo!
