Young Charlie Higgins and his girlfriend, Laurie, are watching an eclipse of the sun when they sight a UFO, which deposits 2 egg-shaped metallic artifacts inside a mine. Analysis proves them to be pure magnesium, a form of the metal rarely found on Earth. After the sixteen-year-old student from South Dakota finds the magnesium, he is warned by a gypsy to be careful in telling anyone about the "Overlords" visit. Ryan and Fitz investigate, but they are hampered by Clara, the gypsy woman, who warns the investigators not to interfere with Charlie's sighting, as he had been chosen to carry out the word of the Overlords.
