Une explosion a eu lieu dans le passé. Cette explosion a conduit à une affaire de meurtre en série connue sous le nom d'affaire Chimera. 35 ans plus tard, une explosion similaire a lieu. Chimera incident, a 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.
