Subtitles: English, Spanish, French Length: 87 mins     The Gang that's all 4 fun - and fun 4 all! Sign up for more manic misadventure with the buffoons in blue, this time featuring rising stars Sharon Stone as a reporter who strikes sparks with Mahoney (Steve Guttenberg) and David Spade as a loopy skateboarder. Cmdt. Lassard (George Gaynes) decides to toughen up neighborhood watch groups by training them to be Citizens on Patrol, or COPs. And guess who the instructors are? The same grads who thought the Fs on their own report card meant "Fantastic." When rival officer Lt. Harris (G.W. Bailey) sees the blue leading the beleaguered, he decides the time is ripe to discredit the Academy. But leave it to our hapless heroes to save the day - bumblingly - by taking to the skies on biplanes and balloons for a frantic finale. All aboard!
