X: The Unknown
When a fissure explosively opens in an English mud flat throughout a army train there, injuring one soldier and killing one other, an American analysis scientist at a close-by nuclear plant joins with a British investigator to find why the victims have been radioactively burned and why, shortly thereafter, a sequence of radiation-related incidents are occurring in an ever-growing straight line away from the fissure.
