An AXE agent is murdered while investigating a Greek tourist agency, Golden Islands Promotions, which has been responsible for sponsoring large numbers of US visa applications.
Then posing as a merchant seaman, Thomas Evans, Carter contacts Leonidas, an old World War II Greek resistance fighter.
Carter (as Prof. Harding) attends a function organized by Golden Islands Promotions where American guests are introduced to young men and women seeking sponsors for their visa applications to the US.
With Leonidas, Carter confirms the camp has been established to train spies and discovers a large cache of weapons and military vehicles.
Gorgas and the Sons of Prometheus are also bankrolled by the Chinese and are planning a coup d'etat to topple the Greek government.
Despite losing much of their arms and supplies in the Baos raid Gorgas demands to launch his coup in the morning – starting with the destruction of the Parthenon.
They will kidnap rich patrons attending a play given by the Golden Islands Promotions recruits imprison them on Papadorus' yacht and ransom them off to their families to obtain enough funds to live comfortably in South America.
He escapes and makes his way to the Theater of Sophocles – an ancient amphitheatre carved into the hillside outside Athens where the play is to be performed.
Posing as a member of the Greek chorus, Carter foils the kidnap attempt and chases Princess Electra into the nearby countryside.
Papadorus and General Lin do not wait for Princess Electra to return with the hostages and set sail for Albania.
