As the Vietnam War dragged on, the U.S. military began desperately searching for any vulnerability in its North Vietnamese enemy. In 1964, it found one: an old Vietnamese folktale about a ghost, eternal damnation, and fear--a myth that the U.S. could weaponize. And so, armed with tape recorders and microphones, American forces set out to win the war by bringing a ghost story to life. Today, The Experiment examines those efforts and the ghosts that still haunt us.
