Simon is a lawyer and lives a pampered life until one day he meets Sam, a released juvenile murderer. Simon's life changes subtly.
Sam looked thin, small, and very pitiful as he was homeless. Simon took him in for a day and helped him on his way back to life.
After that, a series of things happened, making Simon more and more unclear about Sam. He opened up the murder case six years ago and investigated Sam's life with many doubts.
Just when the truth was about to come out, Simon's girlfriend was kidnapped.
Sam on the other end of the phone said with a sneer or arrogance: "Simon, I'm sorry, this is not love, but I need you."
