In the film, it tells the story of Kido pursuing his ideals and love in the small town of Doscan, and falling in love with a primary school teacher named Dora. However, their happiness is short-lived as they are separated and sent to three different concentration camps under fascist government control. In the brutal environment, Kido uses games to help his son maintain his childhood joy and innocence, and his wife feel warmth and hope. The mother and son eventually reunite, but Kido himself dies at the hands of Nazis. The laughter in the story begins with the brake failure of an old car, and then follows with funny encounters with "My Princess", Schopenhauer\’s use of will, comments on racial superiority, and a funny incident of charging into a hall with a horse. All of these moments, including the “most cultured doctor,” who calls someone who is fat and ugly, “why isn’t it a platypus, but a duck?" made me laugh until my stomach hurt.
"If we look at life as a whole, and only emphasize its most remarkable characteristics, it is indeed a tragedy; but if we carefully observe its details, it also has the nature of comedy." "Optimism is a cruel mockery of human disasters." Kido in the film uses his willpower to reach his goals several times, which can be said to be the focus of his winning Dora\’s heart. In fact, his power to flip his fingers in the void has nothing to do with Schopenhauer\’s relationship between reason and willpower, "Will is a brave and strong blind man carrying a bright lame who can guide him." Kido\’s desperate will, because of his kindness and a wise mind, is fulfilled. Willpower was once a stimulant under religious cover in Germany. When it suppressed the gloom and despair of the people, it became a religionism.
