Dragan Miletić Gaga, an experienced inspector of the third department for blood crimes, has specific methods of work that many do not like. Persistent, stubborn, thorough, he persists in his intention to solve the old case. The moment when a famous Belgrade criminal, who is his obsession, is killed, for him is not the end - on the contrary, everything is just beginning. Continuing to search further, Gaga's investigation will lead to minors who have been dragged into a much more dangerous game of drug dealings. This will open a Pandora's box from which new problems, new plots and new unresolved situations will emerge.
