An angry widow dons her ninja gear and takes off for revenge against the gangster who killed her husband in this lively martial arts actioner that revels in its deliberately, deliciously awful tongue-in-cheek dialog that takes a sharp poke at the genre. While the black widow kicks and chops her way to vengeance against the evil villain "White Powder's" gang, police officers Lee Ann Jackson and Lester McQueen stalk her while simultaneously trying to clean up the other trash that litters the streets of their city. In the explosive final conclusion, White Powder meets Mr. Big in the ubiquitous empty warehouse to finalize a major drug deal. Unbeknownst to either of them, the ninja-girl got there first and planted a little surprise for them. In the end, the two crooks get their just desserts, the cops get demoted, and the widow flees to Mexico.
