In 2006, Detective Chang leads a police investigation into a murder committed in a public marketplace. Chang discovers the victim's father has ties to several other families with dead or missing members, and a grim espionage case buried for 50 years in Taiwan's past. Meanwhile, the kidnapped Mr. Hsu is interrogated by a mysterious mastermind. As the truth emerges, the embers of history become a deadly wildfire.
