Journalist Ghianna Karaghiorghi is found dead. Kostas tries to understand who silenced the woman and why, just as he must also cope with the death of his father, an old policeman who served during the military dictatorship of the Greek "colonels".

Having suffered a heart attack, Commissioner Kostas is forced to be hospitalized. Klio, a young and brilliant secretary, identifies the body that emerged from the earthquake, revealing a connection with the Koustas case.
