Oleg Rubtsov cannot stay in one place for a long time and is forced to constantly move. It’s all about his past. He is an employee of the secret unit 0-18, his call sign is Pilgrim. The group took on complex and delicate cases when ordinary law enforcement agencies were powerless: it dealt with the elimination of organized crime groups, gangs and terrorists.

The pilgrim manages to save himself and hide his wife. Now you need to understand who the traitor is and how to live further.
