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