Watch Doorways: Visitors From the Unknown

This documentary explores three stories of the unknown. Join narrator Martin Landau in the search for the truth of what lies beyond the borders of this world. Crop circles: hoaxes or proof of extraterrestrial life? Ghosts: myths or evidence of life after death? Aliens: are we alone, or is someone watching? Eyewitness accounts and authentic footage detail these phenomenon as they have appeared around the world. Dramatic reenactments bring these mysteries to life. Expert testimony brings hard science to support what may otherwise be unbelievable.
