Lobo solitario (2021)

An immigrant has promised his young son that he will talk to his teacher about an unfair scolding, but his limited French prevents him from doing so. After dropping his son at school and leaving him disappointed, he begins his daily job searching routine when he realizes he has lost his son's favorite book, which had been entrusted to him that morning while the two of them were riding the tram. Humiliated and anguished, he desperately travels his new city, still too alien, trying to communicate in a language that he does not speak, to get the book back before facing his son's disappointment again when it is time to pick him up from school.
