The press are covering the apparent suicide of celebrity Shin Hyo Jeong. She supposedly tweeted a suicide message and then jumped from a high rise building. The reason for her death may have been her name linked with a recent sex scandal.
Days earlier we see Kim Woo Hyun, played by So Ji Sub - the saddest looking man I've ever seen. Why so glum, Ji Sub? Woo Hyun is on stage about to give a lecture to a large group of what appears to me to be police cadets. First thing's first, though. Woo Hyun asks which student here has the phone number that ends with 2407. When the timid guy acknowledges his number, Woo Hyun explains why everyone must listen to this "bull shit lecture" about cyber-investigation on such a pretty day, proving that Woo Hyun just hacked into timid guy's phone messages.
Woo Hyun goes on to describe, for example, an illegal online gambling sight. People here in Korea are losing their shirts because they suck at gambling. The server on which the games are played are really in Japan, which looks to be absolutely covered in advertisements all over their buildings. (Does Japan really look like that?) The database server with all the important financial information is in Hong Kong. The best way to take this whole works down is to bust everyone everywhere on the same day. You have to surprise them before they're able to damage the hard drive or all the evidence is lost. (You getting this, future cyber criminals?)
Woo Hyun and his squad, all armed and dangerous, burst into the Hong Kong branch and start splitting heads. Who knew the life of a hacker could be so violent. Unfortunately, the cyber criminals were a step ahead and had set off a self-destruct program on their servers. Oh no, it's the Blue Screen of Death! Woo Hyun desperately tries to save something but it is too late. Then on one of the screens all the zeros and ones come together to form the letter H. Woo Hyun recognizes this symbol. It stands for Hades, someone he's butted heads with before.
The team is being reamed by their director (Jang Hyun Sung - the bad vampire from Vampire Prosecutor) for their failure. He throws a mouse across the room. Woo Hyun walks in just then and reams out the director for touching the computers. (Not only is Ji Sub so sad, he speaks in nothing but monotone. How is this guy an actor?) To make the director's day even worse, the head of the department comes in and tells the director to calm down. Poor picked on director.
Woo Hyun has a meeting with his team as they go over the servers Hades has used in the past. One of the team members holds up something with the letters NPAC on it and all I can think of is the Niswonger Performing Arts Center. No really, it's some kind of new reverse IP tracker. They go around and install these thingies at the sites where Hades hacked previously, believing that old adage that the criminal always returns to the scene of the crime.
Sad Woo Hyun and female team member Yoo Kang Mi discuss Hades over coffee. Turns out Hades has been tapping into police departments and even the Blue House and revealing classified information to the world. It's Wikileaks! Julian Assange is Hades!
As innocent Koreans lose their ability to communicate with each other face to face except through texting, rising star Shin Hyo Jeong wakes up and takes a picture of herself without makeup, tweeting it for her fans to see. One fan appears to be that perennial nutjob, actor Kim Sung Oh. (I'm not putting him down, but whenever you see him in a drama or movie, you're pretty sure he'll be playing a nutjob.) Then the rumors about a sex scandal start to spread about the young actress and Kim Sung Oh looks very disturbed.
That night there's a break for our cyber team as one of their NPAC thingies detect Hades. In a darkened stairwell we see a man with no life tapping away on his laptop. A picture of Shin Hyo Jeong comes up on his screen. We go to Hyo Jeong's awesome apartment which is decorated with huge pictures of herself. Aww, she looks upset as she gets on her laptop and logs into her Twitter account. Ah, now I see. Man With No Life is watching her through his laptop hacked into hers. He also has access to her Twitter account.
People everywhere who are looking at their phones instead of the person beside them see the message that Hyo Jeong just wants to die. Kim Sung Oh is crushed. Meanwhile Sad Sack Woo Hyun and Kang Mi drive to the place identified as where Hades' signal is coming from. It's Hyo Jeong's apartment building. As the two officers start towards the building, Hyo Jeong comes out to meet them the hard way - through the glass roof. Woo Hyun shows no emotional reaction.
The next morning (it's daylight already. What took the police so long to investigate?) the cyber team is taking pictures and some idiot starts hitting on Kang Mi. 'Cause everyone knows a police investigation into a suicide is the perfect time to score a date. Kang Mi asks who is in charge of this investigation. When she learns it is Chief Kwon Hyuk Joo she doesn't look pleased. Several years ago she had worked under the Chief and she had messed up bad, a fact the Chief likes to remind her of when he shows up. Zombie Woo Hyun and the Chief butt heads over evidence collection. Woo Hyun wins by boring the Chief to death.
I'm also bored to death. This is only twenty minutes into the show, yet it feels like twenty hours. So Ji Sub is absolutely terrible! Madonna has better acting chops than this guy, and that's saying quite a bit.
