The Time Tunnel - Season 1 - Eps 2: One Way to the Moon
Doug and Tony land 10 years in the future on the Mars Excursion Module during liftoff. Their extra 335 pounds of weight endanger the mission by putting it over the weight allowance. Everyone believes the time travellers are spies except one man, Harlow. They are forced to land on the moon for a refueling stop, but the ship crashes. One of the other men, Beard, kills Harlow. Beard is a spy. To further confuse matters, ten years in the past at Project TicToc, Beard and another spy, Brandon, are visiting the complex. Brandon sabotages the tunnel and then tries to escape, but Beard shoots his superior to bolster his own cover and his own role remains undiscovered. In the future, Doug and Tony manage to blow up the ""future"" Beard, but the MEM takes off without them. As they are stranded on the moon, their air running out, the Tunnel scoops them up and sends them on their way. (Copyright 2003 Steve Crow)
