在第二次世界大战中,一位不称职的英国军官被他的叔叔 — 战争办公室的一名准将——选中,参加一项秘密行动,从纳粹手中"追回"被掠夺的艺术品。Stanley Windrush has to interrupt his university education when he is called up towards the end of the war. He quickly proves himself not to be officer material. This leads him to meets up with wily Private Cox who knows exactly how all the scams work in the confused world of the British Army. And Stanley's brigadier War Office uncle seems to be up to something more than a bit shady too.
