Mulder seems to be the only person concerned at the prospect that Eugene Tooms is about to be released from the psychiatric institution he's been in for several months. His pleadings fall on deaf ears as Tooms has never been convicted of a crime and the review board find Mulder's claims preposterous. Mulder is convinced Tooms will strike again and begins to follow him while Scully contacts the retired police detective, Frank Briggs, who had helped them in their earlier investigation. An old corpse from a long ago killing helps them out.
