JUDGMENT DAY is a sci-fi/drama that takes place in the present or near future. A man named John Wakefield recalls how he found himself in a hospital with amnesia. The doctor who is helping him plays the videotape John made while he and his team of three scientists traveled on board the aircraft carrier USS TRUMAN to the Atlantic Ocean. While investigating a strange underwater disturbance something went wrong, and John and the tape are the only survivors that can explain what happened.

As he watches this tape of his "home movies" of his expedition John begins to experience flashbacks of the events that led up to his memory loss. Expecting to find a geological explanation, the scientists are confronted with a strange object that has broken through the ocean's floor and is rising to the surface. It is a perfect sphere 500 feet in diameter, and it's origin and purpose is unknown. As John receives increasing pressure to find out more about the object, he is visited by a mysterious apparition informing him that he is the chosen one. The sphere is a test for humanity, and John is to decide the fate of Earth's future. As John races to stop the dangerous experiments the sphere explodes, releasing an invisible plague that sweeps over the world, causing all human life to disappear...except for John. After regaining his memory he realizes his destiny; although he is the last man on Earth, he is the father and creator of a new world. He alone will shape it to merge with the past and future.
