UFO: Shadow Play (1)

The last line of defence in a clandestine war, SHADO is all that stands between humanity and a force of alien invaders - and leading that fight is the uncompromising Ed Straker, commanding Earth's defenders around the clock.

But what happens when the man at the top is pushed too far? After an experiment goes wrong, Straker awakens from a coma with missing memories and strange hallucinations that threaten his grip on reality - but is it the result of alien interference, or has the commander's iron will finally cracked?

Facing danger from within and without, Straker must find the truth... even if it kills him.
