Kim Woo-Hyun leads the cyber investigation team and works to take down an illegal international gambling website. South Korea, Hong Kong and China all cooperate to arrest those involved with the website at the same time. When Kim Woo-Hyun and his team raid the location of the site, the data is destroyed by a program set up by Hades. Nevertheless, Kim Woo-Hyun and his team uses a traceroute to locate Hades.
Meanwhile, an online rumor spreads about a sex scandal involving popular actress Shin Hyo-Jung (Esom). Shin Hyo-Jung leaves the message “I want to die” on her twitter account and then kills herself by jumping out of her apartment. Kim Woo-Hyun and Detective Yoo Gang-Mi (Lee Yeon-Hee), still following the path of Hades, arrives at the actresses apartment and takes her laptop, which Hades hacked.
In the basement parking lot, Detective Yoo Gang-Mi runs into Reporter Park Gi-Young (Daniel Choi). Park Gi-Young asks Detective Yoo Gang-Mi if she is sure actress Shin Hyo-Jung’s last tweet was indeed posted by the actress herself? There seems to be a rumor that her last tweet was not actually posted by herself. Detective Yoo Gang-Mi later checks actress Shin Hyo-Jung’s laptop and discovers that the tweet was not posted from her laptop. The cyber investigation team now believes another person may have been there when the actress died.
Meanwhile, Detective Kwon Hyuk-Joo (Kwak Do-Won) also investigates the death of actress Shin Hyo-Jung. A TV announcement is then made by Detective Kwon Hyuk-Joo’s boss (against the advice of Detective Kwon Hyuk-Joo) that actress Shin Hyo-Jung killed herself.
