From the first meeting between Guido and Dora in the barn tower to the encounter between the two on the way to work, to Guido confessing his love to Dora, in the end Dora cleverly got rid of Lu with the help of Guido. With Dora's entanglement, Kiddo won Dora's heart. Dora ran away from home, and the two got married. The bookstore that Kiddo dreamed of opened, his lovely son Joshua was born, and the life of the family of three became happier.

In the 1930s and 1940s, Italy was shrouded in the clouds of the Nazis, and racial discrimination was very serious. Gido is of Jewish descent, and his application to open a bookstore encountered great setbacks. On Joshua's fifth birthday, the Nazis captured Kiddu and his son. After Dora returned home, she saw the empty building and the messy scene, and understood what had happened.

He and she had no Jewish ancestry, so she insisted on going to the concentration camp with her husband and son. Not wanting to cloud his son's young mind, Kidu lied to his son that this was a game, and he followed the rules of the game. Whoever wins 1,000 points first will get a real tank as a prize. Joshua's toy tank was dilapidated and he wanted a new tank so much that he endured hunger and fear. Guido's game did not harm his son's soul. During the devilish days in the Nazi concentration camp, Kiddo tried every means to secretly pass the Nazi radio, play the music that his wife liked to listen to, and report to his wife that she was safe.
