It's a bittersweet story set against the backdrop of the waning days of the Cold War. Williams, a saxophonist with a Moscow circus, ekes out a living but is miserably unhappy. He lives in a crowded apartment with his entire extended family, with no privacy to express his love for his girlfriend. He sucks up to his superior, standing in line for hours to buy shoes to obtain his favor. He cruises the streets, scrounging for black market petrol for his tiny car. He buffers between his crazy grandfather and the KGB, who want to arrest him for shouting anti-Soviet slogans out the window.
As a rare treat, the circus troupe is sent to perform in New York City. Williams's clown friend, who has talked of little else but defecting, chickens out at the last minute, and Williams who had opposed the scheme as reckless and foolhardy suddenly decides to do it. He hides behind a perfume counter at Macy's, his head inadvertantly nudging the pretty clerk's backside under her skirt. In a scene of comic drama and nobility, Williams stands up to his Soviet boss and demands asylum in the US.
From here, the movie takes an unexpected turn, as life in the Big Apple is not all peaches and cream. Williams must find a job, and his English isn't so good, and he's lonely and disoriented and afraid of being forcibly repatriated. But in the end, he finds the American dream.
