High Treason (1971)

It's been two long and painful years since that failed secret mission in a dangerous region of far-off Kolkata, and the Greek counter-espionage officer, Captain Kostas Varsos, suddenly returns to Athens. With two bullets lodged in his body, Varsos claims that he can expose the mole who is selling highly classified information to the enemy; however, to do so, his superiors have decided that it would be best if he kept his arrival, and his identity, secret. Now, Varsos must remain a ghost at all costs, even if his daughter's life and his wife's happiness are at stake. Will the honourable agent commit high treason in the name of the family?
