The love story of young Countess Natasha Rostova and Count Pierre Bezukhov is interwoven with the Great Patriotic War of 1812 against Napoleon's invading army.

In 1805 St. Petersburg, Pierre Bezukhov, illegitimate son of a rich nobleman, is introduced to high society. His friend, Prince Andrei Bolkonsky, joins the Imperial Russian Army as aide-de-camp of General Mikhail Kutuzov in the War of the Third Coalition against General Napoleon Bonaparte. Part one of the four-part adaptation of Leo Tolstoy's 1869 novel.

Bezhin Lug (Bezhin Meadow) was to be a Soviet film about a young farm boy whose father attempts to betray the government for political reasons by sabotaging the year's harvest, and the son's efforts to stop his own father to protect the Soviet state, culminating in the boy's murder and a social uprising. Assigned to Soviet film-maker Sergei Eisenstein, the filming followed the same path as with his previous effort, "Que Viva Mexico", into cost overrun and over-shooting of footage. Furthermore, Eisenstein's usage of forbidden experimental film techniques outraged his government superiors, who ordered the film destroyed before it was even completed. All that survives are the first and last frames of each shot, preserved by Sergei Eisenstein’s wife, Pera Atasheva. The 1967 reconstruction, by Naum Kleiman of the Eisenstein Museum and Sergei Yutkevich of Gosfilmofond, places these frames in order, approximating the original film.

In 1812, as Napoleon's army invades Russia, Kutuzov asks Bolkonsky to join him as a staff officer, yet the prince requests a command in the field. Pierre sets out to watch the armies' impending confrontation. As the Battle of Borodino rages, he volunteers to assist in an artillery battery. Part three of the four-part adaptation of Leo Tolstoy's 1869 novel.

As Moscow is set ablaze by the retreating Russians, the Rostovs flee their estate, taking wounded soldiers with them, and unbeknownst to them, also Andrei. Pierre, dressed as a peasant, tries to assassinate Napoleon but is taken prisoner. As the French are forced to retreat, he's marched for months with the Grande Armée, until being freed by a raiding party. Part four of the four-part adaptation of Leo Tolstoy's 1869 novel.
