Explosive Evidence (S01E05)

In 1985, an Air India flight disappears over the waters near Ireland. When rescue teams arrive, they find that the crew had no forewarning before the plane was torn apart. Investigators uncover a checked bag that belonged to a passenger who never boarded. On the same day, another explosion occurs at Tokyo Airport, which is soon connected to the flight disaster. Authorities track down the bomb maker and imprison him, but the individual who checked the bag onto the plane remains at large.
