Boris is the youngest son in a big Russian family. Both elder brothers are brave and fierce, but he is thin and small, funny and cowardly. Boris has been secretly in love with his cousin Soga, and the two people often discuss God's issues with laughable overlapping nouns, but Suojia has no response to his love at all.
Napoleon is about to conquer Austria. Everyone is enthusiastic about defending the Russian motherland, but Boris, who has a peaceful mind and a skeptical nature, disagrees. The war is approaching, elder brother Ivan announced that he would marry Anna before going to the battlefield. Suojia, who had always thought that she was the only lover of her cousin, almost fainted on the spot. In a rage, she also announced that she would marry an elderly herring merchant. Soon, the three brothers went on the battlefield together, and Boris did not even forget to bring his butterfly specimen.
The thin, short, stupid and funny Boris started his military career, and Soga also started his own twisted but unscrupulous affair career at the herring merchant's house. The soldiers took a three-day vacation as usual before the war. After watching a "warning drama" warning officers and soldiers not to contract the disease, Boris began to take a vacation. Boris and his uncle went to the opera and met the countess who is said to be lewd and her jealous lover Anthony. Boris first teased the countess, then threatened by Anthony, and finally saw Soga, whom he missed most.
The herring merchant had to fight people in order to maintain Suojia's "innocent reputation", but he got shot while wiping his gun. The corpses were everywhere on the battlefield, Ivan died under the bayonet, and Boris not only survived, but also inexplicably made the battle. Boris was invited to come to the Countess's house for a night of partying, and the next day he received a challenge from the "duel expert" Anthony. Before and after the duel, Boris proposed to Soga, who believed that he would definitely die in the duel, and promised him to marry after the duel.
At the beginning of the duel, Boris was hit in the shoulder by Anthony, but he didn't want to kill and fired a shot into the sky. Anthony was greatly moved and admitted that he had failed. Boris finally got his wish to marry Suojia, and Suojia finally fell in love with this sincere and funny little man. Although the two were poor, they were still living happily. The happy Boris quickly became bored. He began to seriously consider suicide, but soon wanted to be a poet.
The war between Russia and France re-emerged, Napoleon won a big victory and captured Moscow. At the instigation of Soga, the two set out to Moscow, wanting to assassinate Napoleon. On the way, they drove away Sister Dunfran from Spain and pretended to be them to see Napoleon. Napoleon's men found a puppet for him to prevent the assassination, and General Sydney planned to kill Dunforan and then betray Napoleon. Boris mixed into the palace, and Soga was also liked by Napoleon. That night, Napoleon came to see Soga, and Boris stunned Napoleon clumsily, but discussed the murder with Soga. At this time, the people sent to assassinate Dunforan happened to kill Napoleon's stand-in, Boris was also thrown into prison, and Soga took advantage of the chaos and escaped from the prison.
Until the last moment, Boris believed that he would be pardoned and went to the execution ground heroically. When Soga was talking about love with his girlfriend, he saw Boris walking through the wilderness with the god of death, and the two of them were dancing further and further along the woods by the lake.
