خلاصه داستان : سر ارنست یک فرد متخصص و اگاه در انگلیس هست که پس از پیشنهادی که از طرف نیروی دریایی به او می شود تصمیم میگیرد تا در جریان جنگ جهانی دوم خود را اسیر نیروهای المانی کرده و در انجا وضعیت کمپ اسراء را بررسی کند.

Comedy set in World War Two, starring James Robertson-Justice and Leslie Phillips. Sir Ernest Pease (Robertson-Justice) is a self-important scientist who is sent undercover on a bombing mission to monitor the effectiveness of his latest invention, a new-fangled radar. When the plane is attacked, he parachutes to safety - only to be sent to a POW camp, where he takes on the alias of Lieutenant Farrow. There, the somewhat happy-go-lucky bunch of Brits suspect their acerbic new fellow prisoner of being a spy, and all sorts of culture clashes and misunderstandings ensue.
