In 2023, ten never-before-seen archival films were unearthed in Glasgow depicting the life of Scottish missionary living in Palestine in the 1930s and 40s. A Glasgow-based Palestinian filmmaker begins a roadtrip across Europe and the Middle East towards Palestine as a form of archival repatriation to the Palestinian people. Through the form of workshops, Palestinians in the diaspora witness their ancestral past and in the process create a new archive. Before Our Diaspora takes us into a unique journey weaving the archive of an unspoken past to an investigation of a heightened present and uncertain future, exploring the power of film as a form of collective witnessing.
