Athens Homicide Chief Kostas Charistos interrupts his vacation to investigate the discovery of a body after an earthquake on the Greek island where he was staying with his wife, daughter and her boyfriend. But he also has to deal with the murder of a young Albanian couple.

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".

Commissioner Kostas, with a sore shoulder, refuses every visit. The murder of Koustas, a well-known entrepreneur and owner of a nightclub, brings him to the attention of agent Nikos, who immediately competes with Petros.
