The Sixth is a parable about lawlessness and bureaucracy in the aftermath of the Great October Revolution.

The film could be categorized as an "Ostern" type of movie, with a lawman hero who faces up to corruption against the odds, although no one around has any faith in his abilities.

It is set in 1923 and the Russian Civil War has come to an end, although the situation is still dangerous in some regions.

An elusive band of White guards is hiding in the mountains, raiding Soviet institutions and making short work of the representatives of local government.

Recognizing the superior firepower of his well-armed and zealous enemies, he attempts to mobilise the people in the towns and help them regain faith and hope.
