The Bluffer (1969)

For the fun of it, the playful bachelor, Paraskevas, summons up the nerve to pose as the brave Flight Lieutenant of the Hellenic Air Force, John Chalaris, who is still listed as missing in action since WWII. However, pretty soon, Paraskevas will have to come face-to-face with the consequences of his audacious fabrication, when he meets in the flesh the lieutenant's alleged daughter, Yanna. Will Paraskevas be able to sustain his guilty white lie, especially when the seductive secret admirer, Elli, is, too, willing to play games?
