Gerry Anderson and Christopher Burr's classic Earth Defence Force return in Terrahawks: Volume 1 from producer Jamie Anderson.

In the not too distant future, the Earth finds itself under constant threat from Zelda, a blood-thirsty android who, along with her fiendish family and monstrous creations, has established a base on Mars. The only thing standing between this evil queen and her quest for the ultimate annihilation of mankind are the Terrahawks – an intrepid band of heroes led by the stern but fair clone, Doctor Tiger Ninestein.

After a considerable period of inaction, the Terrahawks once again find themselves called into action when Zelda initiates a brand new campaign of destruction and devastation. Facing up against terrifying time travellers, fraudulent financial fiascos, sickening stand-ups, and deadly doppelgangers – their new adventures could prove to be the Terrahawks’ most challenging missions to date!

Featuring eight episodes on four CDs, with a bonus, behind-the-scenes CD featuring interviews with the cast and crew, Big Finish proudly present Terrahawks: Volume 1 - available now on CD and Download!
