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). Written by Marty McKee

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. Written by Luis Carvacho
