The first part gives the bare facts we know about the hijacking. The second part covers the primary suspects listed according to the FBI, media, or public opinion, supported by the show’s best interviews with authors and researchers who covered these suspects.

The third part covers the other major suspects popular among the public but not considered Cooper by the FBI or law enforcement authorities. The fourth part covers some of the major suspects who came forward to police and confessed to being D.B. Cooper.

The last part is dedicated to the wave of copycat hijackings that occurred after the Cooper case. And there were quite a few.
