A bankrupt businessman, Dinos Apergis, confides in his fiancée that he is thinking of committing suicide, but Rita, a poor telephone operator who has overheard the conversation, stops him. Together with two good friends, she follows him to Skiathos and introduces herself as the daughter of Nick Papas, the Greek-American oil tycoon. When Papas comes to the island on vacation with his voluptuous girlfriend Mitsi, Dino's former fiancée, Dino, who has fallen in love with Rita and knows that she is lying to him, suggests to Papas that he treat her as if she were his real daughter. The lies continue on both sides, until everything settles down under the umbrella of love that blossomed where no one could have imagined.
