Q:Generate a question about the following movie plot: When Napoleon (James Tolkan) invades Austria during the Napoleonic Wars, Boris Grushenko (Woody Allen), a coward and pacifist scholar, is forced to enlist in the Russian Army. Desperate and disappointed after hearing the news that Sonja (Diane Keaton), his cousin twice removed, is to wed a herring merchant, he inadvertently becomes a war hero. He returns and marries the recently widowed Sonja, who does not want to marry Boris, but promises him that she will, in order to make him happy for one night, when she thinks that he is about to be killed in a duel. To her surprise and disappointment, he survives the duel. Their marriage is filled with philosophical debates, and no money. Their life together is interrupted when Napoleon invades the Russian Empire. Boris wants to flee but his wife, angered that the invasion will interfere with their plans to start a family that year, conceives a plot to assassinate Napoleon at his headquarters in Moscow. Boris and Sonja debate the matter with some degree of philosophical double-talk, and Boris reluctantly goes along with it. They fail to kill Napoleon and Sonja escapes arrest while Boris is executed, despite being told by a vision that he will be pardoned.
