In a past almost, but not entirely, like ours, the world lives in dread
of a new power, an empire centred in Tibet and led by a megalomaniac.
When the inevitable attack comes, it destroys all opposition, and
capital cities across the planet are left burning. But, in Great
Britain, Professor Mortimer, inventor of a mysterious weapon named the
Swordfish, and his friend and protector Captain Blake, have escaped the
destruction, and must make their way to a secret base.
