On Telos, the Doctor is reintroduced to the Cyber Leader and meets the Cryons, the planet's original inhabitants who will go to any lengths to get their world back!

When sold to places like the USA, a four-part edit of the story was made available; the cliff-hanger was created at the point where the Cryons inform Peri that they will not help her to rescue the Doctor.

In 2014 when the story was broadcast by Horror Channel, they created their own cliff-hanger at about the same point, but a scene earlier where Lytton informs Bates he has a safe route to the landing bay, provided by the Cryons.
