Paul Kersey is again a vigilante trying to find five punks who murdered his housekeeper and daughter in Los Angeles.

High school loser Rodney C. Duckworth (Gary Springer) is known as The Rodent until one unforgettable night when he borrows a cherry-new Chevy convertible and goes cruising for the girl of his dreams. With help of dim greaser Calhoun (David Wilson), hot-rodder T.J. Swackhammer (Brian Kerwin) and some very willing women, Rod goes from zero to hero during a wild ride of near- misses, direct-hits and bra-busting fun.
