The Doctor and Sarah find themselves in an asteroid, on the outer reaches of Earth’s solar system. It’s the future, and humans have colonised this inhospitable place, to mine vital minerals to supply their home planet. However, links with Earth are becoming ever more strained, and forces within the colony are seeking independence. Revolution is in the air.
Meanwhile, in the deepest chambers of the asteroid, a powerful force is emerging. Its influence is growing rapidly. But how will it affect Sarah Jane Smith and her place in future history?

Writer Jonathan Morris said: “If you think of Colony in Space and Frontier in Space as the first two thirds of a trilogy... then here's the final third. It's Doctor Who doing 1970s 'hard-SF'; all about the politics of future Earth colonies (and how they parallel the politics of today). A densely-plotted thriller!”
Producer Heather Challands added: “We're back with another six-parter, a wonderful homage to the original Third Doctor era, and I'm always really excited with what new stories we can tell with this nostalgic format. This story is very political, with growing tensions, growing rebellion and growing telepathic powers. Jonny has done a top-notch job with his script and it's just classic sci-fi.”
Director and script editor Nick Briggs said: “Tim and Sadie are on top form here, with Sadie sounding uncannily more and more like her mum. We’ve got a great cast who really bonded in studio, and our main villain, Zyla Kalstein, is a truly chilling piece of voice work from the BAFTA Award-winning Juliet Aubrey. She’s terrifying!”
Juliet Aubrey added: “I’ve worked with Nick before, I think he’s a fantastic director. I really like playing villains, and Doctor Who’s such good fun. When I read the script, I absolutely loved it, because it was so clear on what we’re doing to our planet at the moment. There are references to how people on Earth have messed it up so much so there is nothing left.”
