: self-ignition of combustible material through chemical action (as oxidation) of its constituents -- called also spontaneous ignition
The thought of inanimate objects -- such as a pile of rags, or an old collection of tools -- spontaneously bursting into flames, is terrifying. Well, imagine if there was such a thing as spontaneous HUMAN combustion! Pretty scary, huh?
For Sam, it's not only scary, it's reality.
Sam always knew that there was something wrong with him, but he couldn't quite figure out the origin of his problem. After years of research, Sam discovers that his parents had been used in a number of atomic-weapons experiments shortly before he was born. The government was attempting to engineer the perfect weapon for war. When the project fails, the government hides all evidence of the project, and it becomes a tightly-kept secret.
Or did it?
As a result of Sam's parents' repeated exposure to radiation, both of their genetic codes were changed, eventually being passed onto their first (and only) child, Sam. Because of the radiation running through his veins, Sam discovers that he has the uncanny ability to make things AND PEOPLE burst into flames.
Talk about getting "hot under the collar"!
"Spontaneous Combustion" is a masterful horror/sci-fi movie by one of the most talented filmmakers in the industry - Tobe Hooper ("The Texas Chainsaw Massacre", "Poltergeist").
