When Joseph was ready to join the Israeli army for military service, he found that he was not the real son of his parents, and when he was born, he swapped with Yassin, a child of a Palestinian family in the West Bank, by mistake. As a result of this discovery, the lives of the two families have suddenly undergone earth-shaking changes, which forces them to rethink their identities, values and beliefs. This film revolves around the long-standing and unsolvable problem of the Israeli-Palestinian conflict, in which two families who are supposed to be hostile to each other mistakenly hold the wrong children and raise them separately-excellent people. Therefore, in this film, we see the hostility of the nation and the exclusion of religion, but it is more a process of mutual understanding and acceptance. "I'm not Jewish anymore, but I'm not an Arab either." Under such a proposition, we find that there seems to be only one starting point to solve this thorny problem-to be a "person" before becoming "someone".
