From a torturous cell in Africa, Abel Powell is released and given the chance to regroup his team of skilled mercenaries for one last job. A top scientist will guide them half a mile underground through an ex-Soviet bunker to extract the vital specimens and information being paid for by a mysterious backer, but what they seek should never have been found!一个多月下来，兄弟俩晚上在金鑫大厦的一层大厅里练拳练腿，深夜的时候回了地下室自己的床上，也会静心修炼丹田里的狂龙劲，白天就开着车子出去寻找父亲和陈家的下落。
