A 12-men jury decides whether a young Chechen boy is guilty of the murder of his stepfather, a Russian military officer. Initially it seems that the boy was the murderer. However, one of the jurors, a foreman, votes in favour of acquittal. Since the verdict must be rendered unanimously, the jurors review the case, and one by one come to the conclusion that the boy was framed. The murder was performed by criminals involved in the construction business. The discussion is repeatedly interrupted by flashbacks from the boy's wartime childhood.
