The director unexpectedly overheard stories about his mother’s family and decided to pick up a camera to explore a century-old history: Topa, a Tayal tribe that once lived in Sanxia but was displaced to Taoyuan’s Fuxing District due to Japanese rule. The main subjects of this documentary are descendants who are striving in their own ways to preserve the memory of Topa. Through their efforts, the connection between their lives and history is finally being brought back to light.
