A secret, high-technology international agency called SHADO defends Earth from alien invaders.

The Power Game is an ITV drama spin-off from The Plane Makers (1963–65), created by Wilfred Greatorex. Broadcast for three 13-episode series, Patrick Wymark reprised his role as Sir John Wilder, who here ruthlessly pursues boardroom machinations and tangled relationships.

Three exciting stories of science fiction adventure set many years in the future. The Earth, once the hub of the Galaxy and its judicial system, is now wasteland. This and its survivors are all that is left of a bygone age after the most vicious intergalactic war ever seen. The Earth's colonies are devoid of any law enforcement system. It is the survival of the fittest (or meanest). The only law left is Ragnarok, a hard-hitting enforcer and his alien friend Smith, who travel the Universe in an attempt to see fair play.

The final moment has arrived. Chocky, Matthew and Albertine return to work together to defeat the enemy and to discover Chocky's secrets for humanity.

Chocky hopes, with Matthew and Albertine's help, to help the human race discover cosmic power, which unlike Earth's finite natural resources, will sustain them for as long as the universe itself exists. But their knowledge has aroused a great deal of interest from the military, and they are willing to take drastic action if they don't get what they want.
