"The control of time is potentially the most valuable treasure that man will ever find." Or so believe the scientists of Project Tic Toc. Located beneath the Arizona desert, the ten-year project's focus is the feasibility of time travel. But when the government reconsiders the project, the scientists have only 24 hours to prove their untested 'Time Tunnel' will actually work. Determined to save the project, Dr Tony Newman and Dr Doug Phillips go through the tunnel - and quickly find themselves catapulted from one historical event to another, barely escaping with their lives as their colleagues back in Arizona race to figure out a way to bring them back home.
