The Lone Gunmen reveal the (possibly fake) secret history of the Cigarette Smoking Man to Mulder and Scully; from a young captain in the U.S. Army recruited to assassinate President Kennedy, to becoming the mysterious man in the shadows at the height of a global conspiracy.

Mulder and Scully investigate the murder of a city official, a crime that doesn't appear to have been committed by human hands. Meanwhile, Scully faces deeply emotional feelings about the child she gave up for adoption.

A chilling secret is revealed when an old friend reaches out to Mulder and Scully in a seemingly impossible way.
