What If? It's an important question but when you ask it, What If I go down the left street than the right? You make your choice and then it's onto the next What If? But then again, in some strange reality, you go down the right street instead of the left one.
That's what this story is all about. What If the Doctor didn't become U.N.I.T.'s Scientific Supervisor? Well the answer lies in this story. The world is a different place and instead of the 1970's, The Doctor (played by David Warner) lands on the eve of the Hong Kong Handover.
It's a unique look at the world if The Doctor didn't save it during the seventies, where there is very little to no plastic(Spearhead from Space), There's a lake in the middle of London (Doctor Who and the Silurians) and The Master now works for the Communists.
If your a Classic Doctor Who fan, it's just fun to look at what's changed and references to other stories are just brilliant.
So If you have the chance to listen or buy this. Do it. You won't be disappointed.
