Little Bo-ri's family has come together – as they do every year – to commemorate her late grandfather. Bean sprouts are missing from their meal and so Bo-ri is sent off to market to fetch some. An unexpected detour takes her to places she has never seen before. During her odyssey, Bo-ri encounters all kinds of people, learns new things and eventually meets a friendly gentleman who could be her grandfather.

On March 26, 1991, five boys set off to the mountain to go frog hunting and never come back to their family. While a documentary producer, detective and professor try to solve the mystery of the incident, one of the boys' parents is a suspect.
