Welcome to the Hotel Intercontinental! We’re in 1970, Budapest, and nothing is what it seems. The hotel serves as a home for spies, counter-espionage, celebrities and small-time crooks. We see all this through the eyes of Ivan the green bellboy who has bigger plans that we would expect. The officer of the internal counter intelligence, the crooked comrade Thoman wants to become the Manager of the hotel, a position filled by the counterspionage officer, the compliant communist Mrs Gyenes. As they both appreciate Ivan's excellent memory and observational skills, they both want to use him for their own goals. The thing everyone in the hotel seem to have in common is opportunism. And Ivan is no different in the beginning, so he sees becoming an informant as an opportunity. Parallel to his growing love for the waitress, Ildi, he begins to see the true colors of the system. By the end he learns not to care only about himself as he turns on his control officer.
