Children... is a 2011 South Korean crime thriller film based on an actual unsolved murder case, the Frog Boys of Daegu.

Plot

On March 26, 1991, the local elections are being held. Since it is a day off school, the five boys set off to the nearby mountain and never return. Their parents try to get the police to investigate right away, but the authorities are more concerned about guarding the election polls. Days later, thousands of police set on the mountain to search for clues as to what may have happened but nothing turns up. The parents take their pleas for the boys’ return to the airways where their story captures the heart, mind and sometimes imagination of the nation. Various theories such as the involvement of North Korean spies and alien abduction comes up.
