Doctor Who: (NA 2) The Highest Science

The Highest Science. The pinnacle of knowledge and a terrible weapon. A legend - nothing more.

Sheldukher. The most wanted criminal in the galaxy. Evil to the core and hungry for power, whatever the cost.

The Chelonians. A vast military power, pledged to eradicate human parasites wherever they are found.

The Doctor. An ancient and wise Time Lord tracking a temporal fluctuation that endangers the universe itself.

Some things should never meet, but as Professor Summerfield is about to discover, the universe is full of coincidences.
