Who, if not us (4K, drama, directed by Valery Priemykhov, 1998)

Teenagers nicknamed Zmey and Tolyasik rob a department store at night. As a result, Tolyasik ends up in a colony, and the court releases Zmey, who is not yet fourteen years old. The guy worries about his friend, tries to ease Tolyasik's fate: he plays the accordion in underground passages, sings, and uses the money he earns to bring parcels to prison. By chance, he meets Gena, a former investigator. A real male friendship arises. Soon the Snake understands that Gena can be relied upon as a father – and this can happen, because the boy's mother meets Gena.
