In 1953, Army scientist Frank Olson takes a fatal plunge from a hotel window; in 1975, a bombshell report ties his death to a top-secret experiment.
Amid a wave of media attention, the government races to placate the family; in New York, Frank visits a doctor known for his unconventional methods.
One trip to New York morphs into two when Frank suffers a setback on the way home; decades later, an apprehensive Eric checks into room 1018A.
A hotel worker overhears a curious phone call the night of Frank's dearth; in 1994, a forensics expert exhumes the body to find compelling new clues.
Frank's growing concerns about Cold War activities raise alarm bells at the CIA; frustrated Eric launches a last-ditch bid for closure.
Thanks to Seymour Hersh, Eric finally learns the truth -- but it comes at a maddening cost; in room 1018A, Frank faces off with two mysterious men.
