Synopsis

Kartal's kidnapping of Ceylan turns the entire balance upside down. As Bozo finds himself dragged into such a massive impasse, Haydar Ali, unarmed and alone, comes face-to-face with death in order to rescue Ceylan. With Ceylan trapped in the mountain house, there's nowhere to escape anymore. As Ceylan reveals the truth behind her marriage to Bozo and the deal she made with intelligence, Haydar Ali begins to question everything he thought he knew. Bozo is forced to confront not only Kartal but his own marriage as well. As the chasm between the life Ceylan wants and the world Bozo has built grows ever wider, an irreparable rift occurs between the two. On the Sultan and Haydar Ali front, however, the emotional balances shift completely. The step Sultan takes opens a new door in Haydar Ali's life; for Ceylan, facing certain truths becomes heavier than ever before. Armed with the truths he's learned, Haydar Ali now finds himself on the threshold of an entirely different crossroads.
