Based on a true story. In World War 2, the Soviet rocket launcher nicknamed "Katyusha", was kept in great secrecy. It had fantastic power but would be lethal in the wrong hands. Disaster strikes, however, when one of these unique killing machines is drowned during an unexpected retreat of the Russian troops. A special unit formed of ex-athletes is sent to rescue the secret weapon, to ensure the Germans can never find it - no matter what it takes. English dub / Russian with subtitles.
