Montage

A kidnapper disappeared 15 years ago without a trace. Five days before the case's statute of limitations expires, someone is found anonymously leaving a flower at the crime scene. A few days later, another kidnapping takes place using the same modus operandi on a similar target. Police team up to solve the case before it's too late as in its previous case. Detective (Kim Sang-kyung) is consulted and he confirms its a similar MO.
