The movie opens with the assassination of a man of unknown identity. A team of three CIA officers, including Jack Chen (Daniel Wu), a rookie, watch through surveillance as a sexy female assassin named Fiona Birch (Marit Thoresen) enters the man's heavily guarded apartment suite and, after having sex with him, kills him by breaking his spine with her bare hands. As she makes her escape in her white Porsche 911 GT3, her car is hit by a rocket. As the officers rush over to extricate her from the wreckage, a woman in a limousine shoots her to death.
