He gets hired in the protection company owned by former loan shark Uncle Ji (Anthony Wong). Jack, an ex- member of a South American commando team, has finally settled in Taiwan as a mere butcher to live a new life. He got married with Hui (Candy Lo) and got her pregnant. A happy and peaceful future is awaiting the new family until his former team-mates arrive in Hong-Kong. Their mission is to kill Hui's father, a powerful Triad boss. Troubles arise when Uncle Ji and Tyler are hired to protect the Boss and when Jack is forced to kill him…
