"Hellbound" immediately gained viewers' attention worldwide as Yoo Ah In, Kim Hyun Joo, Yang Ik Jun and Park Jung Min witnessed the unexplainable phenomenon.
Helmed and written by "Train to Busan" director Yeon Sang Ho, the six-part episode series has maintained its dominance in Netflix's global top TV show since its release.
The thriller-horror series kept the viewers at the edge of their seats with intense and grueling scenes featuring the mysterious creatures.
'Hellbound' Episode 1 Highlights: Three Giant Monsters Terrorized the City
The episode began with people watching Jung Jinsu (Yoo Ah In) preaching for his emerging religious group "The New Truth."
He tells people about his prophecy of angels arriving on earth and bound to condemn people to hell.
"Hellbound" episode 1 also introduced the victim, identified as the 26-year-old Joo Myeonghun, who was sitting at a cafe nervously as if he was waiting for something.
As the clock hits 1:20 pm, he storms out of the cafe as three giant monsters bolted and chased him.
Unfortunately, he could not escape and was left burned to the ground while the creature immediately disappeared.
Due to this, the police step in to investigate the tragic and mysterious death.
Detective Jin Kyung Hoon (Yang Ik Jun) was tasked to dig for information regarding The New Truth, whom the police believe had a connection with the incident.

Detective Jin Kyung Hoon Meets The New Truth Chairman Jung Jinsu
In a gathering, Jung Jin Su tells people that some received a prophecy about them going to hell.
Moreover, he tells his followers that this happens because people choose to sin and forget about repentance, remorse and redemption.
"God has found a way to directly present to you a perfect demonstration of exactly what hell looks like," he said, adding that humans should be more righteous.
At a distance, the detective watches Jung Jinsu deliver his statement, but he is doubtful about the religious leader.
After the gathering, he asked if he could interview "The New Truth" leader and pointed out the possible connection between the case.
While on their way to his home, Jinsu shared his past and what prompted him to start the group.
Jin Kyung Hoon was also stunned that the chairman knew about his wife's brutal death, saying that her daughter, whom the detective saw at the gathering, informed her about the tragic incident of her mother.
The New Truth Offers Park Jung Ja a Decree
"Hellbound" episode 1 also introduced the character of Kim Hyun Joo, who took on the role of lawyer Min Hye Jin, who is handling the case of Park Jung Ja (Kim Shin Rok), the mother of two who recently received a prophecy about her death.
A spirit appeared and warned her that she only have five days to live until her hellbound.
During her conversation with the feisty lawyer, Park Jung Ja revealed that "The New Truth" sent her a decree saying that they would like to broadcast her death, which Kim Hyun Joo finds absurd.
