The series is based on the adaptation of Katarzyna Bonda's prose. After years spent in Great Britain, where she studied and improved herself as a profiler for seven years, Sasha Załuska returns to Poland and almost immediately receives her first assignment. Reluctantly, she leaves her daughter and heads to Łódź, where the police are unsuccessfully looking for a person responsible for a series of arson attacks and explosions. The investigation turns out to be extremely complicated. The way to solve the case is not only the lack of clear evidence and clues, but also the doubts of superiors and associates as to the skills of the profiler. In each subsequent episode, there will be a new trail leading to the solution of the case. Will it be possible to apprehend the perpetrator and complete the investigation with Załuska's help?
