A scientist builds a time machine and accidentally sends his apartment complex manager and a petty burglar to 16th century Moscow, while Tsar Ivan the Terrible travels to 1973.
Set during the early part of his reign, Ivan faces betrayal from the aristocracy and even his closest friends as he seeks to unite the Russian people. Sergei Eisenstein's final film, this is the first part of a three-part biopic of Tsar Ivan IV of Russia, which was never completed due to the producer's dissatisfaction with Eisenstein's attempts to use forbidden experimental filming techniques and excessive cost overruns. The second part was completed but not released for a decade after Eisenstein's death and a change of heart in the USSR government toward his work; the third part was only in its earliest stage of filming when shooting was stopped altogether.
In July 1942, in the Second World War, the rearguard of the Russian army protects the bridgehead of the Don River against the German army while the retreating Russian troops cross the bridge. While they move back to the Russian territory through the countryside, the soldiers show their companionship, sentiments, fears and heroism to defend their motherland.
