Are we alone? From Orson Welles' War of the Worlds to Steven Spielberg's E.T., the very possibility that other life forms exist continues to capture our imagination.

Unexplained crashes obliterating the landscape, reports of secret alien-human breeding programs and mysterious creatures draining the blood of innocent animals, The World's Strangest UFO Stories, uncovers the truth about the biggest, best and most extraordinary alien tales of all time.

Cheeky and just a touch skeptical, The World's Strangest UFO Stories tracks down witnesses and victims who believe they've experienced close encounters of the alien kind, and meets the experts, conspiracy theorists and the E.T. obsessed who have made it their mission to uncover the truth - once and for all.
