Top Secret

Plot:

Top Secret gets under way when George (George Cole), a janitor in a research plant, accidentally comes into possession of the plans for a revolutionary atomic weapon. As George embarks on his annual vacation, the research security team embarks on a nationwide search for the hapless broom-pusher. Meanwhile, the Russians get wind of the incident and intercept George, plying him with liquor and empty promises so that he'll hand over the plans to them. All the while, George never knows what the fuss is about: he thinks that the British and Soviet authorities are interested in his new plans for a modern sanitary system! No one takes Top Secret seriously--certainly not Oscar Homolka, who delivers a bravura performance as a Russian secret agent who wistfully yearns for the glories of the Czarist days.
