The action series begins when young police inspector Aleksandar Jakovljevic, despite his problematic behavior, receives an important case: the murder of the daughter of a prominent contractor who is building the region's largest residential/commercial complex. Aleksander digs into every aspect of the life of the murdered girl, unaware of the danger that is exposed because someone wants to cover up the crime as soon as possible. Aleksander, tortured with the personal pain of his father's never-solved murder, discovers that there might be a link between the two murders, so this becomes his personal mission, and he doesn't know who to trust along the way, not even Police Chief Marjanovic--his boss and his father's best friend--or two women in his life: public prosecutor Marija and young scientist Jelena.
