The Suitcase of the Priest (1978)

In Rome, with his white leather suitcase crammed with thousands of American dollars concealed in a secret compartment, the audacious smuggler, Alkis, catches a plane to Athens, posing as a Catholic priest. However, after a fateful encounter with the beautiful first cousins, Monica and Mariangela, Alkis will find himself neck-deep in trouble, as the girls inadvertently swap their identical suitcases, setting the stage for a wild treasure hunt. Needless to say, the owner of the precious valise, the notorious Mafia lord, Antonio, wants his money back, and under those circumstances, Alkis has less than forty-eight hours to retrieve the case before the mobster's henchmen take over. But, what happens if Alkis finds love, instead?
