Enas apentaros leftas (1967)

Troubled by a pressing question, the young heir and fabulously rich playboy, John Birdas, decides to swap places with the humble white-collar worker, Yannis Bakouras, to determine once and for all whether women are after him for his money or his personality. As a result--in grave need of money to finally walk down the aisle with his long-term fiancée, Rania--Yannis reluctantly gives his consent, only to learn firsthand the answer to John's question. Now, Anita, the beautiful daughter of an affluent businessman, is madly in love with the new Yannis, as John, too, falls for Rania. Will John and Yannis, the penniless plutocrat, talk their way out of the tight spot?
