When a serial killer stalks a Romani neighborhood, a hardboiled police captain teams up with a Gypsy crime boss to bring the killer to justice.

He is a distinguished, respected family court judge. She is an honest and principled woman who has saved many marriages from destruction, made sure that many children receive the affection and love they deserve, and has always been on the side of justice.

In the story that begins in a suburb of Istanbul, the events between Kenan Cesur, who shouldered the burden of a momentary mistake, and Zeynep proceed with an adventure full of ambition, passion and regret. Imam Yusuf and Teacher Nilüfer, on the other hand, become a beacon of hope for the young people whose dreams are gradually disappearing in the dark road they enter by saying “Nothing can happen for once”.

A special team of four is established by the Istanbul Police Department. The team has all kinds of different talents. These four people, who have experienced many things in their past, start working together to solve grisly murders.
