In the series’ opening minutes (shown in
the first trailer for the series), massive, Hulk-like monsters appear out of nowhere to chase a man through the busy, daylit streets of downtown Seoul. The monsters beat the man to death and then burn him to a crisp with their otherworldly powers. Then, they disappear just as mysteriously as they came, through a portal into what seems like another realm. As you might imagine, there are not only many bystanders to this event, but many of them film the horrific killing, with the footage going viral.
The first three episodes of Hellbound are less concerned with explaining how this supernatural event happened and more interested in depicting how different elements of society will respond. People are understandably terrified, and looking for answers that can fit into their understanding of the world. Traditional institutions—from law enforcement to broadcast media—don’t have them. We see just how in-over-their-heads the Seoul police department is by following world-weary detective Jin Kyeong-hoon (Yang Ik-june). Jin is one of the officers assigned to the Hapjeong Station murder, which is being treated as a “typical” killing rather than one perpetrated by demon-monsters. Jin and company look for an explanation as to how this tragedy happened, but are soon waylaid into dealing with the fear-driven harassment and violence that result from the phenomenon.
