Quan Ngoc Minh is a humble London businessman whose long-buried past erupts in a revenge-fuelled vendetta when his teenage daughter dies in a senseless act of politically motivated terrorism. His relentless search to find the terrorists leads to a cat-and-mouse conflict with a British government official Hennessy, whose own past may hold the clues to the identities of the elusive killers.
