In 1979, 20 years after it was set up, Project Tic-Toc was shut down by the American authorities. All hope of retrieving scientists Tony Newman and Doug Phillips, lost in the Time Tunnel in 1968, has been abandoned.

In 2025, four people are brought together by a need to reopen the Arizona base and reactivate the Time Tunnel in secret. From there, they must try to find Doug or Tony because something they have done in the past has changed the present - and not for the better. The world is now under the power of Rakervia...

1.1 The Shudder, November 14 2025 by Gary Russell
The team come together and send Lewis Haworth and MB back into the past to try and find Tony Newman and Doug Phillips... but they have opponents whose existence they are completely unaware of...

1.2 Too Close to the Sun, January 5 1941 by Marc Platt
England. World War II. It's January 5th, 1941. A momentous day for air pioneer Amy Johnson. But this might also be the day she disappears...

1.3 The World, the Flesh and the Devil, December 24 1645 by Martin Day
MB and Lewis find themselves in the grim heart of the English Civil War - and on opposing sides. The battle of Naseby is over - Cromwell's New Model Army has defeated the Royalist forces commanded by Charles I - but everything is in tumult, the future uncertain.

"Irwin Allen's The Time Tunnel had the potential to be the most interesting and clever of all his shows, but the story never got a resolution - and that was the launchpad for this new 2025 version," said Gary Russell, producer and script editor of the new series from Big Finish. "Time travel is also dangerous - as the great writer Ray Bradbury once warned, be careful not to tread on the butterflies..."

Robert Napton, SVP & Publisher, Legendary Comics, added: "I first started listening to Big Finish's Doctor Who audios at the Gallifrey One convention 30 years ago, so it's been fun to work with Big Finish and our friends at Synthesis to bring another beloved classic series back to the modern era. I am glad producer Gary Russell, and executive producers Jason Haigh-Ellery and Nicholas Briggs, are so passionate about returning to the world of Irwin Allen's The Time Tunnel."

Producer Dominic Martin said: "The scripts are just sublime, we have these wonderful characters thrust into situations and times that are certainly intense for them - but a joy for us to listen to!

"Our heroes try to blend into history on their quest to find Tony Newman and Doug Phillips, but can they truly succeed as they cross paths with the doomed pilot Amy Johnson and the armies at the heart of the English Civil War? It's such an exciting set of stories, with that underlying tension as it genuinely feels like every action our team makes could have tiny or devastating consequences - and you just don't know what!"

Lead actor Seán Carlsen, best known to Big Finish listeners as Narvin in the Gallifrey audios, said: "I was aware of The Time Tunnel, but I'd never seen it, so I looked at old episodes. And it is fantastic. It's a wonderful lost sci-fi gem!"

His co-star Safiyya Ingar (The Eleventh Doctor Chronicles) said: "I'm a sucker for the found family trope! Misfits who get together who, in any other reality or timeline, would never have met or had anything to do with each other. But here they are. How do they make it work? And you know they're going to become unexpected friends."
