About the title
Seventeen-year-old Artyom is invisible at home and a rebel at his vocational college. He has a best friend, Kostya, and they pull off all their pranks and provocations together. When the college administration draws up an unofficial list of dangerous teens — "bombers" — Kostya, purely by chance, ends up in first place, which makes him popular among the other students. Kostya basks in the newfound attention — and betrays his friend, convincing their classmates that he, Kostya, is the sole leader and mastermind behind all their pranks. Artyom then decides to prove who is really "bomber number one" here. But a girl named Kira unexpectedly appears in his path, capable of influencing his dangerous plan.
