The Heart of a Tramp (1968)

With his gravely ill father on his deathbed, Nikos promises to do everything in his power to fend for his younger brother, Andreas, who is his spitting image, and lands a job as a stevedore. As Nikos sacrifices his aspiration of a better future with his sweetheart, Anna, in the meantime, Andreas, who is studying to become a lawyer, squanders his time and his brother's hard-earned money on ephemeral pleasures and gambling. Now, Nikos has no other choice but to risk life and limb as a sponge diver to earn enough money to support his wastrel of a brother. But fate has a cruel plan in store for Nikos.
