Benny Chan Muk-sing spins this high-octane police thriller. Noted character actor Lau Ching-wan plays Zhu, a respected though short-tempered cop who finds himself transferred to the Emergency Unit after smacking his superior. When his friend and former colleague Yang (Francis Ng Chun-yu) is murdered during a mob turf war, Zhu vows vengeance, assembling an unofficial posse of his Emergency Unit underlings to take out the gangsters. After a bold robbery of millions of U.S. dollars from the Interpol HQ -- in a scene that was lifted straight out of Michael Mann's -- the gangsters are desperate to get the cash out the colony. Their solution is to highjack a transport plane. Of course, Zhu and the gang cotton on to their dastardly plan just in time, leading to a hair-raising battle within and on top of the aircraft.
