Tornado (1964)

Andreas, as the owner of a semi-central building in Athens, intends to give it away in exchange for compensation, but the building houses a nightclub owned by Stefanos, who is strongly opposed to this. Stefanos decides to prevent this by any means necessary, even if it means sacrificing his personal happiness with Kaiti. Since Stefanos knows that Andreas won't marry Fani unless he marries his sister Vasso first, he tries to seduce her. So he does not hesitate to use various schemes to undermine her relationship with Stelios, a fellow Greek from Congo who is a friend of Fani's brother, Alekos. When he finally succeeds, he begins to slander Fani as well, thus destroying her relationship with Andreas.
