When Streaker knocks the beautiful Melinda Boffington-Orr into the mud, Trevor is told to train his dog by her father, the local Police Superintendent. Then the dreadful Charlie Smugg bets Trevor that Streaker can't beat his Alsatians in the agility test at the local dog show. If Trevor loses, it's a bath in the terrible horse trough again. Of course, Tina will help, but how on earth are they going to train Streaker in time?
