Mark, a historian interested in time travel, spends years attempting to build a time machine to save his ancestor who died in battle. After many failed attempts with scientists, he finds an old gypsy woman who tells him through her crystal ball that he will succeed. Mark then partners with an Egyptian scientist and they finally complete a functioning time machine. However, in their haste to test it, the scientist accidentally sends them hundreds of years into the future during a nuclear war instead of the past. They take shelter and survive the night, emerging to an empty wasteland, with Mark realizing it was all just a vivid dream.
