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.

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.
