Father, Behave Yourself! (1967)

Instead of studying to get his law degree, Thomas "Tom" Papastafidas--the frivolous son of the affluent countryman, Antonis Papastafidas--indulges himself in bustling Athens' pleasures. To help his superficial boy get back on track, Antonis decides to pay a visit, only to find himself lured by the big city's bright lights and its intense delights. Now, Antonis is head over heels in love with a young temptress--Thomas' friend, Betty--and no one seems able to make him change his mind. Is there any hope for the ripe Casanova?
