Inspired by a television show featuring a kickboxing heroine, a woman named Kathy (Julie Suscinski) enrolls at a martial arts school in this low-budget action-comedy. When Kathy learns that the school is a front for drugs, prostitution, and blackmail, she uses her new skills to take the bad guys down.

A nerd is harassed by punks, and is the object of ridicule at work. Enamoured by a co-worker, he buys a tape series on how to be cool, summons up his nerve, and goes to the co-worker's house, only to find her in the clutches of another co-worker. Dejected, he goes out on the town and parties with some babes, but when their friends, who turn out to be the same punks that harassed him earlier, trash him again something snaps, and the irritants in his life begin experiencing an attrition problem.
