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.

He teams up with an equally ambitious professor who hopes to make a name for himself by solving the crime where police failed.

The professor’s theory, which seems to have quite a bit of compelling evidence behind it, takes the pair in a direction that the police were reluctant to investigate.

Their clothes were tied into knots used by sailors and bullet casings were found in the shallow, makeshift grave.

Kang Ji-seung meets with the police officer who investigated the missing boys' case ten years ago.

The officer reveals that on the night after the boys disappeared, he came across a mysterious young man who is always seen fishing in the area.

The officer decided to keep this a secret since Korea has a statute of limitation on major crimes and in 2006 it ran out on the case.

To add to the mystery, the area where the remains were found had been searched numerous times since the boys were known to play there and yet, almost a decade later, their bodies suddenly show up there.

However, Kang Ji-seung falls asleep and the culprit, realizing he is being watched, takes a picture of the reporter's car.
