National boundaries, which just won the award for best original screenplay at this year's French film Caesar Award, is a work that reflects the issue of race relations. In this film, the fate of an Ethiopian boy named Shlomo has changed dramatically in a few days: in a refugee camp on the border of Sudan, he was woken up by his mother and put on a truck from Israel to protect Ethiopian Jews. Before leaving, the mother just said, "survive, adapt." The child didn't know what his mother wanted him to adapt to, so he set out on the road away from home in a large group of people. In the crowd, there was a woman who had just lost her child. Out of sympathy and pity, she pretended to be the boy's mother, compiled a genealogy and background for him, and brought him to Israel. However, when Shlomo first relied on the new mother, the woman died of a serious illness. Lonely, he was finally adopted by a kind-hearted local couple. In this advantageous family, he received unlimited love, grew into a smart and handsome black guy, and won the hearts of white girls. But for many years, he was always confused that he was not a real Jew, often poured out his nostalgia for his hometown to the moon, and missed his mother all the time.
