On a warm spring day in 2015, Grandma Tamayo and the TAMAKI family, the largest Taiwanese immigrant family on Yaeyama Islands of Okinawa, goes a journey back home where they’d long left before World War II: Taiwan. The people who emigrated from Taiwan to Okinawa became the political refugees under the 30-year U.S. occupation. TAMAKI family is the one who had experienced the complicated history. By revisiting Taiwan, they little by little steer out of the disorientation of their memory and identity. This is a heartwarming home movie spanning 80 years about how a family together wades through and eventually revives in the tide of the vicissitudes in East Asian history.
