A decent Korean thriller that fits the mold of so many similar genre films of late. Home invasion, cybercrime, stalking etc. It doesn't do much to improve the formula, but it will do for a casual watch.

The film minimizes blood and guts, instead playing up the psychological terror that victims suffer from cybercriminals. Our protagonist really does go through considerable distress with hardly any way to protect herself since the elusive villain's methods are scarily effective. He often hides in plain sight, and the screenplay cleverly keeps him hidden until late in the story. Thus we have both a mystery and a stalker thriller that plays its cards straight, with little diversion from the main plot.

It does progress into something more conventional later on, and it might have been more memorable if it strayed from the norm. But we'll have to do with what's presented here, and that's a polished piece of tension building that doesn't do anything to impress, but just about scratches that thriller itch before you move on to something better.

The movie is a very good investigative thriller ? Writing & screenplay is excellent ? Meanwhile for Shin Hye Sun headlining this movie, I knew she's gonna be great for this role and it really is, her acting performance is freaking insane. She will never disappoint you. Though i hardly see any film but by chance i happened to watch this movie . Felt like as if this is happening in real. Not even once i liked to get up from my chair. My soul really got happy with the character which hae-sun played with seriousness. Not only she looked extremely beautiful but also did full justice with the character. I cry with her Oh my God ! The last scene was most powerful and later Salute to the Director and all team for making such films. And my good wishes will always remain with Hae-sun for bringing true smile to my face. The ending is so crazily scary, It will make you think - hard.

I didn't expect much from the premise of the movie, which is about online shopping, but was pleasantly surprised by the dramatic turn of events that happened.

The movie centers around a woman who is the victim of an online scam but when she tries to expose him she discovers that the scammer is a serial killer.

The cast's performance is pretty good with the main character Soo-hyun played by Hae Sun Shin, who is definitely brilliant when it comes to showing her range through different types of movie genres. I can feel the character's emotions really well through the screen, from anger, annoyance, despair to fear. The detective characters, played by Sungkyun and Tae-oh, did bring some flavours to the table as their presence may lighten the mood.

I find some of the action scenes pretty violent, but effective and memorable as it definitely had me on the edge of my seat especially towards the end.
