The story of humble London businessman Quan (Chan), whose long-buried past erupts in a revenge-fueled vendetta when the only person left for him to love - his teenage daughter - is taken from him in a senseless act of politically-motivated terrorism. In his relentless search for the identity of the terrorists, Quan is forced into a cat- and-mouse conflict with a Irish government official (Brosnan), whose own past may hold clues to the identities of the elusive killers.
