It became the custom that Cossacks lives in Russia turn to be dramatic and unpredictable, Be it Don Cossacks, Amur or others. The same is about Amur Cossack Aleksey Butov (B.Brondukov). He leaves for the battle-front during the World War I, and everything gets under way: in 1915 he gets injured and is taken prisoner, then escapes, participates in a revolution, fights during the Civil War on the side of the Red Army. And now, in 1923, he finally comes back home, to Amur. But everyone considers him to be deceased. His wife couldnt wait and married his best friend, they got a daughter, and his native son doesnt recognize him. All that is insufferable for him, but he needs to keep on living, and also defend the borders from the Chinese and White Guardians gang, raging around. And Aleksey starts handling all that.
