Martin in the Clouds (1961)

Martin and his girlfriend Zorica are two students who live as subtenants in separate flats. Since that situation has devastating effect on their love life, they yearn after the place of their own. When Martin's landlords go to the hollidays, it seems that their prayers, at least temporarily, had been listened to. However, the idilla is very short one, because other people also want to use the situation.
