Director Shin Tae-ra teams with screenwriter Lee Yeong-jong to adapt author Yusuke Kishi's 1997 novel concerning an insurance investigator investigating a brutal series of murders. Jeon Jun-oh (Hwang Jeong-min) is a bespectacled former bank employee who now makes his living as an insurance investigator. Summoned to the formidable country estate of potential client Park Chung-bae (Gang Shin-il), Jeon is unnerved by his host's jittery behavior, and shocked to find the body of Park's seven year old son hanging lifeless from the ceiling. Everything in this house has a grim aura, including Park's wife Shin Yi-hwa (Yu Seon) - a grieving cripple whose recent stab at suicide is evidenced by the jagged wounds that mar her wrists. After touring the house, Jeon becomes convinced that Park is in fact a psychopath attempting to carry out an elaborate insurance scam. Not only does Jeon suspect that Park killed his own son, but he believes the murderous patriarch is now intent on doing away with his wife as well. When Jeon's attempt to convince the authorities of Park's guilt seem to fall of deaf ears, the sleuthing insurance investigator becomes obsessed with the prospect of uncovering the truth about this strange case. Unfortunately for Jeon and his unsuspecting wife Mi-na (Kim Seo-hyeong), this mystery is much deadlier - and deeper - than anyone ever imagined imagined. ~ Jason Buchanan, Rovi
