The Greek Connection (1973)

After a botched attempt to strike it rich and a long stint in jail, expert safe-cracker Zamanos returns home. Once, the double-crossed ex-convict had let himself get carried away by the false promises of ruthless drug lord Mouratis. Now, the same man threatens the life of Zamanos' beautiful little sister Eleni, his only relative. But fate plays cruel tricks on people. And as the two sworn enemies cross paths, with the police hot on their trails, Zamanos and Mouratis find themselves forced to do one last job together: rob a fancy Lebanese pusher of his precious cargo of pure heroin to set themselves up for life. However, revenge is a dish best served cold.
