A detective thriller about revenge that time cannot control. In 1984, several arsons were committed in Korea, which were named "Chimera" - it was this mythical creature that was depicted on lighters found at the crime scenes. Three people died back then. And now, 35 years later, a similar case occurs. Detective Cha Jae-hwan, FBI profiler Yoo Jin, and Dr. Lee Jung-yeop take on the investigation. Each of them hides a secret - the "Chimera" case turns out to be too personal, too traumatizing for the heroes. As we know, this fictional creature breathes fire, so burning in the search for the criminal (or his imitator) will be easy in both literal and figurative senses.
