Furin returns from his long absence, his old colleagues looking at him as if they've seen a ghost. Rakova immediately demotes Victor in favor of Furin to the head of the homicide department. Although Victor is in dismay, Rakova reassures him that his favor will not go unrewarded.

After Furin takes matters into his own hands, Victor confronts him. A paranoid pop star seeks help from the department, but the circumstances on his case are uncertain. However, when the pop star's security detail is murdered, Rakova urges Furin to take the case.

An old man stumbles upon a troubling note and rushes to the station for help. When multiple women have been kidnapped, the department will have to act quickly in order to save them. Furin takes the younger investigators under his wing. Rakova's transfer is revoked, causing Victor to panic about his future.

Furin pursues the lead given to him by Rakova; the fourth and final member of their old team. Ghosts from the past raise tensions even higher between Furin and Vitya. After releasing a former criminal, Furin plans to use him to get closer to The Baron.
