Having just arrived at his new post at the Athens homicide division, Chief Inspector Max Richter is immediately called to duty: a young musician has been found shot dead in her apartment. Together with his Greek colleague Petros Makropoulos, he immediately begins the investigation. The two are initially very skeptical of each other, but together they manage to identify a suspect. However, the more information they uncover, the more obscure the case becomes, and they soon find themselves in the middle of a transnational corruption scandal.
