A kidnapper disappeared 15 years ago without a trace. Five days before the case’s statute of limitations expires, someone anonymously leaves a flower at the crime scene. A few days later, another kidnapping takes place using the same method on a similar target.

On the way to his mother’s funeral, a detective accidentally hits a person with his car. He takes the body with him and puts it into his mother’s coffin. The moment he feels relieved, he receives a call. This caller insists that he saw the detective’s hit-and-run, but instead of asking for money, he wants to know about the body’s whereabouts, leading to a do-or-die showdown of the witness and detective.
