Sixteen year old Lee Hyukjae has a great life traveling where the careers of his father, an investigator, and mother, a renowned violinist, take him...until his parents are found murdered.

Left with only a mirror and notes from his father's last case, Hyukjae goes into hiding at the remote country home of Leeteuk, his father's college buddy, and Leeteuk's teenage son Donghae. The mysterious mirror must be a clue to what happened to his parents, and when images appear in it-people and things that don't exist - Hyukjae and Donghae painstakingly gather evidence. But the killers want the mirror, too, and danger threatens the teens at every turn.
