In the final episode, Erin refuses to abandon her quest to find Mohammed's family, even though it takes her on a hazardous journey into Gaza. Len's diary records how, in 1947, Jews take to the streets celebrating the British decision to withdraw from Palestine. A crucial vote at the UN means their own state is finally within their grasp. In Haifa the mass exodus of Arabs has started and Len fears for the safety of Mohammed, his son Hassan, and their family. He exhorts them to abandon their home and leave the city by boat. Mohammed reluctantly agrees and Len takes them to the port but in the chaos at the dock gates, something unexpected happens. In an effort to make things right, Len makes a promise to Mohammed: a promise that will ultimately determine the fate of both their lives.
