We were introduced to a policeman, Jin Kyeong-hoon, as the team leader was updating them on a new cult, New Truth. I was rooting for him to defeat the cult and whatever monsters that had been shredding and burning people. Amidst the chaos, a vigilante group called The Arrowhead appeared and decided to take matters into their own hands.

Basically, the monsters, according to New Truth, were Angels sent by God to punish the sinful one. And The Arrowheads job was to expose their sin and also punish anyone that was in the Angels way.

Jin Kyeong-hoon team up with Min Hye-jin to help a family when a single-mother got a message that she will be next to die.

Episode 4 continues 5 years later as Bae Young-jae became the next main character. I lost interest here because I was invested with Jin Kyeong-hoon. But, I wanted to know the conclusion of the series.

The New Truth had a new leader who gained profit by broadcasting live the moment the Angels punish someone. Another group emerged to help anyone who got the death message to avoid the live broadcast. The New Truth decided to team up with The Arrowhead to track this group and eliminate them.

The ending foreshadowed a 2nd season. I don't have any theory to share to avoid touching on sensitive topic. I mean each religion have their own believe. What do the atheist and Scientologist think about it? I love to know their opinion.
