Ten years after one of Dr Richard Long's military experiments went wrong and killed eighteen US servicemen and a medical assistant, he has become a recluse in the small town of Jerome, Montana. He still conducts scientific experiments at the local base and his only social activity is going fly-fishing with Tim Mason, a cook in the local run-down cafe.
