After suffering life changing injuries in the line of duty, bomb disposal
officer Poon Shing Fung (Andy Lau, Infernal Affairs, House of Flying
Daggers) turns his back on the police. But when a devastating series of
bombings sweep Hong Kong, the police suspect their former ally may be
involved after he is found unconscious at a crime scene. With memory loss
and recalling fragments of his former life, Fung sets out to uncover the
truth and find out who he really is.
