Representatives of the special corps are engaged in work on investigations of particularly complex crimes. They are one of the best representatives of their field, who are excellent professionals in various fields of activity, ranging from criminology to psychology. Active agents of this unit take over cases related to crimes committed on sexual grounds, as well as cases related to children. Of course, many of these cases are particularly cruel, so the operatives have to be prepared for any turn of events. For example, almost every second agent suffers from constant psychological overstrain, which affects the work. Attempts to find evidence and subsequently find the criminal are sometimes unsuccessful, so we have to look for new ways to solve the tasks set. Each new episode of the series is another exciting story, a new case, the investigation of which is developing right before the eyes of the audience.
