The only unsolved hijacking in U.S. history: On November 24, 1971, a man calling himself D.B. Cooper pulled off the perfect crime - hijacking a plane, collecting $200,000 ransom, and vanishing into thin air. This true crime documentary explores the cold case that has baffled the FBI for over 50 years.

What started as a routine Thanksgiving Eve flight became America's greatest unsolved mystery. Cooper calmly handed flight attendant Florence Schaffner a note claiming he had a bomb, showed her the contents of his briefcase, and made his demands. After receiving the ransom money and parachutes in Seattle, he released the 36 passengers and ordered the crew to fly toward Mexico City.

Somewhere over the dense forests of southwestern Washington, Cooper lowered the aft stairs of the Boeing 727 and jumped into a raging storm - never to be seen again. Despite one of the longest-running investigations in FBI history, Cooper's true identity and fate remain unknown. Did he survive the jump? Was he an experienced paratrooper? Or did he perish in the wilderness?

The mysterious death of U.S. Army intelligence officer Ralph Sigler remains one of the Cold War’s most disturbing secrets. In April 1976, he was found dead in a Maryland motel—wired to a lamp, electrocuted, and left behind with nothing but a cryptic note and bruises no one could explain. Just hours earlier, he had phoned his wife and said, “I never lied.”

Sigler had spent years pretending to betray his country, secretly feeding disinformation to the Soviets while operating as a U.S. double agent. But somewhere along the way, the mission blurred. The people he trusted turned against him. And when Army interrogators pushed too far, Sigler vanished—only to reappear under fatal circumstances no one ever accounted for.

What really happened in that motel room? Was it suicide, Soviet retaliation, or something far more calculated?

If you follow true crime, Cold War espionage, and the real stories behind intelligence operations gone wrong—this is one you won’t forget.
