A successful businessman Boris Ryashhentsev becomes a victim of the classic contract murder: in a parking lot, right next to his own car, he is attacked by killers on motorcycles. The guard of the entrepreneur, Teeth, following the order of the boss, opens fire to defeat, but the killers manage to avoid retaliation. Arriving at the scene, expert Rykov immediately draws attention to the stunning feature of this murder. It seems that the bullets fired from a Zubov pistol ricocheted off the electrical panel and just hit the chest of the unfortunate Ryashhentsev! The interrogated guard and his partner, as well as a saleswoman from a neighboring stall, repeat the story of bikers word for word, and this version quickly finds confirmation.
