Leung is the bodyguard of a Chinese Triad boss, Wong, to whom his loyalty is unrivaled. Living in Hong Kong, Wong requests that his bodyguard travel to the UK to protect a young British woman, whose true identity is known only by Wong himself. Even Wong's son, Yuen, is kept in the dark, which leads to a betrayal that threatens to destroy the family and all that his father has worked hard to protect.
