Plot
The film is based on an incident, the so-called "Disappearance of the frog children." On March 26, 1991, five elementary school students who said they were going to hang out on a nearby mountain to catch frogs never returned, a case that sparked a national controversy.
The children's bones were discovered on Mount Waryong in Dalseo-gu, Daegu-si in 2002, 11 years after they disappeared. This case remains unresolved since the statue of limitations expired in March 2006.
