A young city girl named Jingjing was looking for her disappeared boyfriend in his home- town. Instead, she found her boyfriend’s grandparents, Shuimu and A-Fang, living in the remote village. Jingjing accidentally re- veals a mysterious relationship of 60 years: Shuimu kept a secret friend called Zhong- sheng. Mute and having lost his memory, Zhongsheng has a feeling that he might leave the world soon. He had asked Shui- mu to prepare funeral supplies for him. He is also terrified of becoming a lost ghost in the netherworld. Shuimu asks for Jingjing’s help to find Zhongsheng’s true identity in another remote village 300 kilometers away. The road trip sent the three on a foggy jour- ney through spaces and times.
