Renowned nuclear weapons researcher, Dr. Gregory, is not only dead – he’s charred to a radioactive cinder in his lab at the Edward Teller Nuclear Research Facility near Oakland, California. Scully and Mulder are called in as it’s a death on Federal property and they confront a tight-lipped Federal bureaucracy whose job it is to stop questions before they’re asked. Scully and Mulder hit dead ends, closed security clearances and classified documents no-one  wants them to see.  But that doesn’t stop them ripping the lid of Dr. Gregory’s illegal project – a destructive nuclear explosive that leaves virtually no radioactive fall-out.
