This action thriller co-written by filmmaker Luc Besson stars Jet Li as Liu Jian, a Chinese intelligence officer in Paris on an assignment that finds him in the midst of an international conspiracy. When Liu's investigation gets too close to uncovering the truth, his life is seriously jeopardized and he's forced to creatively employ his martial arts skills, which includes using a pool ball and the French flag as defensive props. In the meantime, romantic sparks fly between Liu and a sexy witness (Bridget Fonda), while the agent discovers that a trusted French peer (longtime Besson featured player Tcheky Karyo) is actually the double-crossing criminal mastermind he's seeking.
