She coerces them to take her along for the ride in their soupedup 1966 Chevrolet Impala. The unorthodox sheriff, Captain Franklin Vic Morrow, obsessively pursues the trio in a dragnet, only to find his outmoded patrol cars unable to catch Larry, Mary, and Deke after they ditch the Impala for a 1969 Dodge Charger RT 440 at a flea market. ........
