Plot

Haydar Ali Aslan lost his family as a child and grew up abroad. On the day he proposes to the woman he loves, he kills Bedrettin Hanoğlu, the man who murdered his father. To protect the woman he loves, he agrees to work with the intelligence service and infiltrate one of Turkey’s most dangerous underground cartels.

He wins the trust of the cartel boss and serves three years in prison. But the deadliest test comes when he walks free: the woman he never forgot is now married to the man closest to him.
