Plot summary

In a series of amusement parks, something deadly is happening. Rollercoasters are flying off their tracks, and people are dying. It soon becomes apparent that these are not a series of coincidences, but the work of a psychopathic extortionist who is placing explosives on the tracks. The FBI is called in to investigate and traces the crimes to a young man. But even after the man gets his ransom, he plans to blow up another rollercoaster...this one at a well-known park in California. Will the FBI be able to arrest him before he can carry out his murderous plan...or will another rollercoaster go off the rails?—Derek O'Cain
