Commissioner Emil Popov grooms Martin Hristov from a young age to be an undercover agent in mob boss Petar 'Djaro' Tudjarov's organized crime gang. After graduating from the French police academy, he is sent into jail to build his criminal credibility, where he meets pimp Zdravko Kiselov, better known as Hair. Hair turns out to be a crucial contact for Martin, as he turns out to be part of Djaro's gang. Martin attempts to infiltrate them by warning them of an ambush and gaining their trust. Despite the favor, Martin attracts the suspicion of Djaro's right-hand man, Ivo Andonov, who brings him in with reluctance and caution. Martin saves a woman from an unknown assailant and sleeps with her, before learning she is Sunny, Djaro's girlfriend.
