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.

A hotel worker overhears a curious phone call the night of Frank's death. In 1994, a forensics expert exhumes the body to find compelling new clues.

Thanks to Seymour Hersh, Eric finally learns the truth -- but at a maddening cost. In room 1018A, Frank faces off with two mysterious men.
