After finding fans far & wide with the Hong Kong action classics City on Fire & Prison on Fire, Ringo Lam directed his first English-language film, Undeclared War, in 1990. American & Hong Kong law enforcement must team up to thwart a terrorist conspiracy in this crime action thriller that mixes the Hong Kong cast of Danny Lee, Rosamund Kwan & Tommy Wong with Olivia Hussey ( Romeo & Juliet), Peter Lapis & Vernon Wells ( Mad Max 2: The Road Warrior).
A terrorist group plans to carry out attacks when American business delegates visit Hong Kong in order to advance their political agenda. The CIA catches wind & sends agent Gary Redner (Peter Lapis) to Hong Kong to investigate the case. He gets paired up with local cop Lee (Danny Lee), & these two very different detectives immediately get off on the wrong foot. However, the two must work together to stop the terrorists violent plans.
