Lee Jung-Soo, imprisoned for the murder of his parents, drags the police in an enigmatic game in order to entertain himself. He asks to meet with the former FBI agent Gil Soo-Hyun, whom he considers being the most likely to solve his riddles. But the new hobby of Lee Jung-Soo puts the lives of many people in danger.

Gil Soo-Hyun notices Lee Jung-Soo's restlessness: why would a murderer want to save his own victims? Unless he himself is a mere pawn in an even more sordid story...

The new team is officially created. Gil Soo-Hyun, Oh Dae-Young and Jin Seo-Joon obtain their very first case: the driver of an abandoned car vanished on the highway.
