It is among the most controversial of phenomena and the hardest to explain. It is said to consume its victims from the inside out, turning them to cinders while leaving their surroundings relatively untouched. Sometimes the fire is so localized that the victimís torso and head are destroyed while the legs and hands actually remain intact. One victim was engulfed in a fire so intense that it decimated her in less than 20 minutes. In THE UNEXPLAINED: SPONTANEOUS HUMAN COMBUSTION, believers in the phenomenon go head-to-head with skeptics and fire investigators. Interviews include emergency personnel who answered 911 calls and saw the remains of victims, fire experts who investigated deaths that have been purportedly caused by S.H.C., relatives of S.H.C. victims, as well as witnesses to S.H.C. deaths.
