Watch The Time Tunnel Specials in Australia

In 2006, an experiment of the Department of Energy in hot fusion to produce energy releases a storm in time along 240 minutes, changing history. Only the personnel in the core of the laboratory know the true story and now they need to fix points in the history that have been punctually changed. The bureaucrat and former Marine Doug Phillips is a family man that is recruited by his friend Flynn to join an expedition to 1944 due to his great knowledge of the Battle of Hürtgen Forest in Germany. The team formed by Doug, Flynn, Toni Newman, J.D. and Wix is assigned to find a monk from 1546 that has been accidentally transported to the spot and is the carrier of Black Plague.

An extended version of the first episode, running about 55 minutes rather than the regular 50 minutes. It contains material that was cut from "Rendezvous with Yesterday" and then added to two subsequent episodes: Tony arriving alone outside of the Time Tunnel complex ten years earlier, when he was unknown to the security forces and Doug Phillips (see "End of the World"), and Tony being reunited with Doug in a prehistoric rainforest (see "Chase through Time"). In the pilot film it is Senator Clark, who suggests that Time Tunnel personnel should just go outside the base to save Tony; however, in "End of the World" since Senator Clark is not in the episode, his lines are given to the technician Jerry.

In 1976, there's an outbreak of a disease that no one has seen before. All what they know is that rsembles a disease that existed at around 1871, and that a Dr. Henderson was able to save most of his patients but the Chicago Fire destroyed his records. Dr. Earnshaw the doctor looking for a cure was approached by a man, Jeffrey Adams, who believes that he could help him. It seems that a Dr. Amos Cummings has prefected the art of time travel, and the plan is for Earnshaw and Adams to go back to 1871 and learn how Henderson cured his patients. But a glitch in the machines computers sends them the day before the fire not four days as intended.

Silent footage shot with a home movie camera during the filming of the pilot.
