The Forty-First (Russian: Сорок первый) is a 1927 Soviet war film directed by Yakov Protazanov based on a novel of the same name by Boris Lavrenyov.

Across the white sands of Central Asia, the Red Army's detachment is advancing, led by the Commissioner Yevsyukov.

Tensions arise between both: the officer is a well-educated aristocrat who is both amused and impressed by the crude attempts of Masha, a fisherman's orphan daughter, to compose Agitprop poetry.

When their camels are stolen, their commander decides to send his captive on a boat to their headquarters in Kazalinsk via the Aral Sea.

The Red soldier treats the White officer when he catches a fever and is slowly charmed by his manners, while he is overcome with gratitude and begins to call her 'Man Friday' with affection.
