The Cybermen are hiding in the London sewers and turning humans into cybernetic slaves. On Telos, two slaves make a bid of freedom and find a way to escape the planet for good.

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 Russell creeps up to the Doctor and Peri in the sewer with his gun.

In 2014 when the story was broadcast by Horror Channel, they created their own cliff-hanger at the point where the Doctor and Peri enter the sewers.
