Underdog (1965)

Without remorse, the ruthless landlord and father of the pampered rich girl, Keti, evicts from their home the hapless family of the talented pianist, Nikos. After renting a small room in kind-hearted Anna's house, Nikos, his beloved, Lisa, and the band travel to Thessaloniki to perform in the local nightclubs to make ends meet; however, fate has other plans. Now, Lisa wants to have nothing to do with Nikos--and to make matters worse--she has vanished completely from his life. What has happened?
