Come by on the First of the Month (1965)

Much to her disappointment, Anna, a conscientious but inexperienced debt collector, learns the hard way that chasing overdue payments for a living is one of the most challenging jobs in the world. After all, almost all her clients respond the same way: "Please come by on the first of the month". As a result, Anna enlists the help of an experienced collector to show her the ropes. At first, things looked promising, but then Anna encountered a tough nut to crack: the suave bachelor, Dimitris Stefanou. Now, Anna must work twice as hard to get the job done. But what happens if love gets in the way? Can the debt collector fall for the debtor?
