Synopsis
The story revolves around Efe, a fearless police captain working in Istanbul’s organized crime division. Efe has spent months trying to gather enough evidence to arrest Kartal, a powerful crime leader who controls the Romani neighborhood of Çıngıraklı. Despite knowing about Kartal’s illegal activities, Efe cannot find the proof necessary to bring him to justice.
Kartal is respected by the residents of Çıngıraklı because he protects his community from outside threats. Although he operates illegal businesses, he considers himself a guardian of the neighborhood and values loyalty above everything else.
The situation changes dramatically when a series of brutal murders shocks the city. The victims are all found with three pennies left at the crime scene, leading the media to nickname the killer “The Three Pennies Murderer.” The murders are connected to İrfan, a mysterious man seeking revenge for events from his past.
To stop the killer, Efe and Kartal are forced to put aside their rivalry and work together. Their uneasy partnership uncovers hidden secrets, dangerous enemies, and shocking truths that threaten everyone involved.
