The city suffers a series of grave arson cases, all announced and executed with masterfully designed bombs by self-stylist Prometheus, 'Purifier of sin'. MacGyver helps old-fashioned fire inspector Earl Stringer, a friend, analyzing the bombs. At the next call, they go in together and Mac tries to defuse the bomb, but it still kills Earl. Mac works on his theory that the arsonist is the same person who set a fatal fire to a café years ago. He finds means and traces, but becomes the living target of bombs without timely warnings.
