During a bomb attack in southern Iran during the Iran-Iraq War, a boy named Bāshū runs behind a truck and falls asleep. When he wakes up, the truck has arrived in northern Iran. He flees for the road construction in fear of an explosion, and after passing through a grove, reaches the paddy field of a woman named Nāy, who, in the absence of her husband, lives and works with her two children. The boy’s language is incomprehensible to her, just as Bāshū cannot understand her local language. Nāy’s husband is opposed to the presence of this stranger in his home. When Bāshū finds out, he leaves the house, but Nāy finds him in the rain, beats him up, and takes him home. Nāy writes in a letter to her husband that she adopted Bāshū as her son and gave him food and shelter. When her husband returns, he loses his hand one day. Bāshū helps him and later succeeds him as head of the family.
