S01E12 finale
Chimera incident, serial murder and explosion crime that shook the year of 1984, takes place exactly the same thirty five years later in 2019. Just like the terrible explosion in the past, the murder of the crime is called Chimera, a monster in the Greek myth with the head of a lion, body as a goat, and tail as a snake that shoots fire through its throat.
Jae Hwan finds out that the bullet found at Joong Yeop's crime scene was one that police officers were not issued to fire. Later, after watching an unsettling recorded video of his mother's interrogation, Jae Hwan rushes off to see his mother, who is now under supervision. Meanwhile, Kim Hyo Kyung appears on an internet show and reveals new facts about the Chimera Killer.
