The Air Stewardess (1971)

A youthful and harmless fabrication on a sun-kissed April Fools' Day will pave the way for a playful romance in the seductive city of Rome, as the beautiful flight attendant, Chloe, decides to give in to Stefanos' subtle and pleasant courtship. Both lovers indulge themselves in a sweet fantasy--she, an independent but poor woman posing as an affluent heiress, and he, a wealthy shipowner playing the underpaid employee. Under those circumstances, three days in the ancient Roman capital are more than enough to ensure a meaningful relationship; however, a lie is always a lie. Will the charming couple survive the inevitable revelation?
