In Byzantine Empire, a man (hired to repair the caslte) is wrongly accused of killing a young girl and sentenced to death.

Murat was very young when his parents separated. He left his father's mansion with his mother and never saw him again. However, this distance does not prevent him from suspecting his father's suicide. As far as he knows, his father is not the type of person who would commit suicide. He believes there is a secret behind this. The old man, before his suicide, had lost his mansion—his last remaining asset—at the gambling table where he sat for the last time. Before dying, he wrote four names on three gambling cards, leaving behind unanswered questions. Murat will set out to uncover the meaning of this clue, whose significance he does not yet understand.

Mustafa lost his mother and father on the same day. His father abandoned them for a dancer, and his mother committed suicide that day. The little boy was suddenly left all alone. His father was now an unforgivable criminal in his eyes. He would ask his father to account for the pain he had caused him with the gun he left behind as a memento. But there was no need for that. His grandfather tells Mustafa that his father is dead. In reality, his father had committed murder because of the woman he had abandoned his family for and had been sent to prison. Mustafa learns this truth twenty years later. His old anger is reignited. He goes to Istanbul to find his father. But he doesn't even know who he is looking for. The only thing he can cling to in the corrupt world he has fallen into is love.
