A mysterious radiation leak in the Baku area places part of the city under complete quarantine. An explosion in an underground laboratory hidden since Soviet times turns the zone into both a dangerous area and an attractive hub for illegal business. Evacuation is impossible, and the territory is fully sealed. While scientists struggle to contain the radiation, criminal networks establish a new balance of power through the smuggling of an unknown substance. Recently released from prison, Bahadir secretly returns to the zone, caught between his past, a desire for revenge, and the criminal underworld. At the same time, police officer Ilyas follows the trail of this dark network. Science, crime, and human nature collide at a single point. The Zone becomes not only a physical threat, but a place where the darkest side of the human soul is revealed.
