After the previous one seemingly eliminated the possibility of any more supernatural threats in Ollyverse, the third miniseries in the saga brings a more grounded story, focusing on Sergei Lazarov. After losing Michael and Gavin, Sergei and Scott get two new members of the team and, under the guidance of Major Konstantin, declare war on Moscow's kingpin of crime, Maksim Sazkaljovich. The mission goes awry and, even though Maksim is killed, the fallout of the mission is far from what Konstantin had hoped for. Maksim's empire is taken over by his daughter Olga, who is trying to maintain a form of peace, while her brother Vasily, who was crippled in the mission, vows to take vengeance on Sergei and his team. Sergei starts receiving creepy texts which seem to be coming from Aleks Marchant, reigniting his guilt-driven anxiety, distancing him from his team and making him question his secret love relationship with Olga. Vasily joins forces with his cousin Voz to find a way to take his revenge without Olga's knowledge, but things get complicated with the arrival of his American girlfriend Carmella. Cat-and-mouse games intensify, as Sergei and his team try to solve the mystery of Aleks' ghost and a powerful entity starts pulling strings which could destabilize all of Russia, and the world.
