Season 5 explores the disintegration of Ibro’s life. Following the death of his wife (Kame) in previous seasons, Ibro is left to raise his son, Borislav (Borko), alone. The season documents his desperate, often clumsy, and ultimately heartbreaking attempt to save his son from the criminal life that has consumed their family. It is a masterclass in tragic acting by Penev, showcasing a man broken by grief and powerless against the new generation of criminals.
