The Hustler (1964)

Financially hard-pressed and jobless, Kanelos Karabatsas, a hapless young man, decides to grab the opportunity when his ill tour-guide cousin, Kimonas, with whom he shares the same surname, asks him if he could lend a hand and fill in for him. Completely unqualified, but in desperate need to make an easy buck, Kanelos will soon find himself in a real predicament, as a string of unforeseen situations stemming from the cousins' synonymity, lead to an unexpected encounter with Kimonas' sweetheart, Lina, and her tough-as-nails brother. Poor Kanelos, how will you manage to get out of this mess?
