Haydar Ali avenges his family's murder and ends up in prison, where he falls into the orbit of Turkey's most dangerous crime cartel. Recruited by intelligence to dismantle it from within, he must earn the trust of its ruthless boss — a man who becomes his closest ally. Three years later, freedom brings the deadliest complication yet: the woman he never stopped loving is now that same man's wife.
