Hye Jin is an investigator that has been training to become one for numerous years, and finally has a case to solve. The first case is a multiple murder of 5 people dead within 15 hours, all in the same area. Do Kyung Soo is the primary suspect, which everyone is pointing fingers at him, believing he's the one. As Hye Jin interviews KyungSoo numerous times, she starts to feel as if it wasn't him...but she has no evidence for it. But that's not the only thing she feels involving Do Kyung Soo...

After sober, some horrible shit happened.
