Chain Reaction
A prison bus with over a dozen criminals on board has an accident and rams another car, in which Dr. Douglas Madsen was on his way home. Most of the prisoners die. Four of them survive, one of them severely injured. After having killed all the guards, they head for the woods. They take Dr. Douglas Madsen hostage. Suddenly a huge house appears in the middle of the woods. The leader of the group, Arthur, emphasizes that he will kill Douglas and every single member of the "family" if his wounded brother would die. Meanwhile some members of the family show strange behavior, and very soon mayhem breaks loose.

A free-radical reaction is any chemical reaction involving free radicals. This reaction type is abundant in organic reactions. Two pioneering studies into free radical reactions have been the discovery of the triphenylmethyl radical by Moses Gomberg (1900) and the lead-mirror experiment described by Friedrich Paneth in 1927. In this last experiment tetramethyllead is decomposed at elevated temperatures to methyl radicals and elemental lead in a quartz tube. The gaseous methyl radicals are moved to another part of the chamber in a carrier gas where they react with lead in a mirror film which slowly disappears.
