After the arrest of Djaro and a serious shake-up of his position, Martin remains in the underworld as an undercover cop. This time his enemies are more and stronger. His new enemy is Ivo Andonov. After the death of his father and Sunny, he has nothing left to lose but to continue fighting crime to the end and at any cost.

The journalist Elitsa Vladeva also joins the actions against the underworld. Martin now knows that only by legal means is the fight doomed.
