Episode 8

Prison doctor Petya extracts from the Doctor the recipe for a lethal cocktail he used to eliminate his victims. In exchange, the death-row inmate is transferred to a hospital for treatment—so the Doctor will live a while longer. The prison warden spots Japanese visitors in town and offers them the chance to kill one of the condemned prisoners, with generous payment. Meanwhile, they need to deal with Kostya once and for all. The comrades' choice falls on Sasha, who had a good relationship with Volkov. Sasha hesitates to deliver the fatal injection and turns to Natasha for help. If Kostya is eliminated, the illegal business inside the prison walls can thrive without any obstacles.
