Ali (Amir Farrokh Hashemian), a boy from a poor family, accidentally lost his shoes when he was helping his sister Zahra (Bahare Seddiqi) get her repaired shoes. In order to avoid being punished by his father (Mohammad Amir Naji) and mother (Fereshte Sarabandi), he begged Zahra to keep it a secret for the time being, saying that they could wear his shoes to school alternately, and promised to buy her a new pair of shoes. Ali originally hoped to use the money he and his father earned from working in the city to buy Zahra a new pair of shoes, but his father's accidental injury dispelled his dream. When Ali saw that the prize for the third place in the city's long-distance running competition was a pair of sports shoes, he decided to participate in the competition, but he missed the registration date. After several requests, the teacher (Dariush Mokhtari) made an exception and allowed Ali, who was outstanding, to participate in the competition. On the field, Ali kept reminding himself that he must get third place!
