O kalos mas angelos (1961)

Even though silver-tongued Antonis Charis is a suave and good-mannered gentleman, unfortunately, he is also unemployed and penniless. However, after saving Nelly--the beautiful but frivolous daughter of the austere businessman, Diamandis Narlis--from an embarrassing situation, his unique set of skills will land him a job as the company's newest employee. Now, Antonis is indispensable to both the firm and Nelly's family, and as the two of them get to know each other better, an unexpected romance will bloom. Is Antonis, indeed, the Narlis' good angel?
