Two scientists with a secret time travel project find themselves trapped in the time stream and appearing in notable periods of history.

Scientists Tony Newman and Doug Phillips are the young heads of Project Tic-Toc, a multi-billion dollar government installation buried beneath the desert. They have invented a Time Tunnel, which will allow people to visit anywhere in time and space. While testing the tunnel for an impatient senator, Newman and Phillips became trapped in time, and each week coincidentally found themselves at the site of an important historical event, be it the Siege of Troy, the sinking of the Titanic or an assassination attempt on President Lincoln. Sometimes they traveled into the future, and battled alien invaders. Ann MacGregor, Gen. Kirk and Dr. Swain are the scientists trying to fix the malfunctioning Time Tunnel and bring Doug and Tony back to the present (1968).—Marty McKee <[email protected]>

The year is 1968, and Doug Phillips and Tony Newman are are working on a top secret project beneath the Arizona desert called "tic-toc". The project has been 10 years in the making, and a visiting senator wants to see if this project really works, or he will cut the funding for it. To prove that it can work, Tony Newman turns on the time tunnel and goes back to the year 1912, and is on board the Titanic, which would sink hours later. Doug Phillips goes into the tunnel to help Tony, and both are stuck hapless in time. They are catapulted each week to a new adventure in history.—Doug Leighton

The U.S. government has a $7 billion project to build a device to allow travelling in time. A senator is sent by congress to the installation in order to inspect the situation and decide if the government should spend more money on it. As the senator seems to be disappointed, Prof. Tony Newman takes his chances and uses the Time Tunnel in a trip to the past to demonstrate the device's efficiency. He arrives aboard the Titanic in 1912 a few hours before it sank. Prof. Douglas Phillips goes to rescue him, but things go wrong and both become lost in time.—Luis Carvacho <[email protected]>
