Frankie Howerd stars in this comedy as a lowly boot-boy who is a terrible coward. He only goes to war in 1914 after he has been hypnotised to 'save England'. With the German master plan tattooed on his backside (this is the only way he could get the plan back to the British), he goes to the British headquarters, with the Germans in hot pursuit, to try and 'hand over the plans'!!!
