About the life of the Russian biologist Ivan Michurin. 1912 year. Having rejected American offers to work abroad, Michurin continues his research in the Russian Empire, despite the fact that his ideas are not perceived by the tsarist government, the church and idealistic science. Michurin is supported by prominent scientists of the country and he continues to work hard. After the October Revolution, a small Michurin garden in the city of Kozlov (the biologist's homeland) becomes a large state nursery.
