Jang Ja-yeon

Friends since childhood, three young professionals struggle with their compulsions—schizophrenia, sex addiction, and infidelity.

On the day of the hundreds billion dollar contract deal just ahead, Jung suddenly disappears after he leaves for a convenient store. Inspector Kim who is desperate to get an exclusive crime case in the hope of drawing media attention finds out that Jung had many jealous colleagues and starts to investigate the case focusing on embezzlement and kidnapping. On the other hand, inspector Park finds out that Jung’s fiancee Mi-sun, a sales manager at the insurance company, has recently took out a life insurance policy on Jung’s life and points her as a suspect. The more investigation goes further the more case gets mysterious and things start to get out of control as a missing case develops to an assault, a kidnapping and finally to a murder.
