On the same day, in the same accident, Wei loses his pregnant wife and Ming loses her fiancée, leaving their world with nothing but emptiness. Buddhist rituals give 100 days to mourn for the dead, and like two mice lost in a labyrinth, Wei runs around in circles, hitting walls, and still ends up where he began. Ming calmly creeps down a determined path, seemingly moving forward, but towards a fatal dead end. No matter how they choose to mourn, the pain and sorrow is all the same. With the 100th day approaching, they wonder if they will ever be able to say goodbye.
