Tricksters (1963)

To expose the shady business of an unscrupulous, money-oriented plot seller, Pygmalion visits him in his office posing as an interested buyer. In the meantime, convinced that Pygmalion knows the exact location of a buried treasure, a pair of opportunistic layabouts watch his every move, waiting for the right moment to strike. Now, as an unexpected ally joins forces with Pygmalion, two wealthy Greek-American friends arrive in Athens, Greece, willing to pay good money to buy a vast plot of land. But, who are they, and what are their true intentions? Will the tricksters get what's coming to them?
