Joseph, an 18-year-old preparing to join the Israeli army for his mandatory military service, lives at home in Tel Aviv with his parents. A blood test for Joseph’s military service reveals that he’s not their biological son. During the Gulf War, Joseph was evacuated from a clinic along with another baby, and the pair was accidentally switched. While Palestinian Joseph went to Tel Aviv with the Silbergs, their actual Jewish son Yacine was brought to the West Bank by an Arab couple, Said and Leila. The revelation turns the lives of the two families upside down, forcing them to reassess their respective identities, values, and beliefs.
