Witness stories from around the world, united by one of the most basic human needs: a desire to find purpose and meaning in our lives. First, 19-year-old Cha Cha , a devout evangelical Christian college student, hopes to reconnect with her faith after a recent trauma shook her to the core. Next, Reshma Thakkar, a young Indian-American Hindu woman from Chicago, travels to the banks of the Ganges River in India for the Kumbh Mela, joining millions at the world's largest spiritual gathering. Meanwhile, in Budapest, Hungary, 13-year-old Mendel Hurwitz prepares for his bar mitzvah, the Jewish ceremony recognizing the transformation from boyhood to adulthood. Mendel's synagogue in Budapest once faced extinction, and this tiny Jewish population is struggling to keep its culture alive. In the final story, Terry Gandadila, an Aboriginal elder in Australia who is nearing death, passes on the wisdom and knowledge of his tribe to his grandson. Together, they walk the "songline," an ancient road map that the tribe believes reveals how the world was created and how to live life in accordance with the spirits of their ancestors.
