Following the crisis in Ukraine and Russia’s involvement in Syria, the world is closer to super power confrontation than at any time since the end of the Cold War. Now a committee of senior former British military and diplomatic figures comes together to war game a hypothetical ‘hot war’ in Eastern Europe, including the unthinkable - nuclear confrontation.
　　The War Room faces a scenario that has haunted western strategists since civil war broke out in Ukraine: potential Russian military involvement in the Baltic States of Latvia and Estonia. Like Ukraine these countries have sizable Russian speaking minorities, but unlike Ukraine they are members of NATO, whose founding treaty states that an attack on one ally is an attack on all of them. Because of this, western analysts regularly war game a situation where Russia seeks to exploit ethnic tensions in the Baltic and test the strength of the NATO Alliance.

澳門回歸前三天，五位情深意重的殺手。殺手阿和(張家輝飾)與妻子阿靜(何超儀飾)帶著剛滿一個月的孩子重返故地，阿火(黃秋生飾)與阿波(林雪飾)奉黑社會老大大飛(任達華飾)的命令來追殺阿和，但另一對好兄弟阿泰(吳鎮(zhèn)宇飾)與阿貓(張耀揚飾)聞訊，為了情義前來阻止。沖突在阿和家突然爆發(fā)，又迅速重歸平靜。最后他們決定一起做一宗大買賣來解救阿和，在謝夫(張兆輝飾)那里，擺放在他們眼前的是兩個選擇：暗殺蛋卷強(林家棟飾)或者搶奪一噸黃金……最終他們選擇了前者，然而卻在餐廳和死對頭大飛不期而遇，一場惡戰(zhàn)難免。
