The Acquaintance

Kidnapping

Late at night, a car accident occurs. Do Kyung-soo, a criminal psychologist, drags his feet out of the car and assesses the situation when he is kidnapped by unidentified assailants.
He is now locked in a narrow space surrounded by gray walls. He shouts to the outside, but no one replies. After a while, he hears someone’s footsteps. A bottle of water and some food are provided through a small window at the bottom of an iron gate. Kyung-soo talks at the person behind the gate, but they just walk away without a word.

Suspect profiling

Do Kyung-soo closes his eyes. What comes to mind is only one thing: Who kidnapped him? Since becoming a police officer, he expected there would be many that would hold a grudge against him. But after he quit being a cop, he didn’t think that would be the case anymore. Not so. Once he became famous as a criminal psychologist, he faced even more threats.
He recalls the usual suspects from over the years. After a long time of reckoning, he narrows the suspects down to three people. Yet, he cannot be sure which one it is.


Escaping

Three days have passed after being locked in. The kidnappers have yet to make a move. The only thing Kyung-soo can do is eat the meals they give him. He feels a tingling pain anytime he slightly turns his right shoulder. It seems that his injury from the car accident has gotten worse. He intentionally rams his shoulder into a wall. And that night, he pleads in pain toward the surveillance camera. The gate that has been shut for three days opens. The kidnappers appear. They examine him and try to inject him with some painkiller. At that moment, Kyung-soo launches a counterattack and succeeds in escaping from the narrow room.
He flees from the house in the middle of a forest and runs down the cold mountain path in a frenzy. After a while, he reaches the highway. A car approaches. He flags it down.
He explains to the driver what happened and gets into the passenger’s seat. Somehow the interior of the car feels familiar. He immediately senses that this is his own car. He turns and looks at the driver’s face. It’s his own face. Now he knows who the culprit is.

Acquaintance

Several years before, Kyung-soo’s son killed a girl in the underground parking lot of their apartment building. Kyung-soo hid the girl’s body and framed another person using his profession as a profiler. The man who has the same face as his is the girl’s father. Kyung-soo is chased by the man with his face over and over. Consumed by guilt and fear, he decides to give everything up. Then, an unbelievable truth is unveiled: His son was not the real culprit.
