Soyeon, an active journalist, receives a call from a serial killer. Revealing himself as Soyeon's childhood friend Sangjoon, he is a fugitive on the run after escaping a mental institute and killing 18 people. His request is surprisingly a personal interview. Agreeing to help her friend redeem himself, Soyeon does as requested and brings a Japanese cameraman to the killer's hideout. Sangjoon threatens the cameraman to record everything in one continuous cut as he explains the reasons for the murders.
From murder to rape, confusion and terror, Soyeon desperately tries to make sense of the situation and prevent a terrible fate.
