The third in the four part series that tells of how the cybermen exploit a war between humanity and androids for their own ends.
Forced to flee earth for their own survival, our heroes from the last part have to battle the cybermen, before an exciting piece of space action where help comes their way.
Even so, some androids aren't too happy they'll have to work with humans, even though their survival depends on it.
And off they head, to find and destroy the cybermen.
Not quite as gripping as part two, although it does have it's moments. This does serve mostly to give the androids more screen time and introduce the central theme - see the title of this review - but having gotten this far, you will want to know what happens next. And part four is well worth it
