In a secret world, a family's code of honor is under threat and an ancient way of life is knocked off its axis by one boy's act of grace. Raised on the tough Manchester estates, a young English boy, Dezzie, becomes loyal friends with a young Chinese boy, Yasin, protecting him from local gangs and bullies until Godfather Kai Chang arrives to take the teenager back to Hong Kong. Ten years later, Yasin returns to Manchester and invites Dezzie to be a part of the family, a triad family with unbreakable laws, a code of honor and traditions dating back two thousand years. But as the friends' journey progresses side by side, a firm wedge of hate and betrayal is soon to drive them apart - and against each other.
