Plot

A group of Russian mobsters have stolen a huge supply of paper for printing U.S. currency, and are now flooding the market with counterfeit bills. When a young woman named Mickey (Jill Ritchie) working for the mobsters decides to turn herself in and hand over a data CD to the police, she is shot and killed, but not before handing the disc to an unsuspecting Tommy Lee (Phillip Rhee). Despite working with the police as a martial arts instructor, Lee doesn't go to the cops with the disc, but instead goes on the run, giving the mafia time to kidnap his daughter Stephanie (Jessica Huang) to hold as a hostage in exchange for the disc. When Lee catches the mobsters fleeing in a C130, he raises himself on a fire engine and casts the mobster's own bomb into the plane as landing gear doors close.
