Investigations into the murder have begun. And while the new Deputy Chief is determined to change everything, a mysterious file reaches the hands of the Director of Police Laboratories.

The two victims have one thing in common: a tattoo on Medusa's head. Later, after his visit to the University, Lieutenant Sklavis finds a note with the name of a girl.

A new suitor for the position of the leader of the organization makes his appearance. Meanwhile, police officer Carra continues the investigation, while a creepy video reaches the hands of Velissaratos.
