Soviet Border.

The Soviet Far East and Manchukuo are separated by a border river, on one side of which Russian White Guards have settled in a small Manchurian village, while on the opposite bank lives the Vlasov family. Wanting to destroy the Vlasovs, the White Guards break into their house. A detachment of soldiers led by border guard commander Captain Tarasov comes to their aid. A long and exhausting battle ensues. Based on literary materials by P. Pavlenko.
