The Fourth Doctor's first trip in the TARDIS brings him, with Sarah Jane and a very skeptical Harry Sullivan, many thousand years into the future to Nerva, a space station in Earth's orbit.
The Doctor is amazed to discover that Nerva is nothing less than an ark for the human race. Having evacuated Earth when solar activity threatened all life on the planet, these few hundred survivors have been drifting in suspended animation for thousands of years.
Even more perplexing is the discovery that someone has sabotaged Nerva's vital systems. The Doctor reactivates the systems, and one by one, the human race begins to awake from its enforced deep sleep. The future of humankind appears secure until the Doctor learns that the larvae of the Wirrn, a hostile insect race, are also aboard.
Review [***½]
Oh boy, oh boy, oh boy! This is truly great stuff! Tom-Doc, Sarah and Harry go timehopping and pop up inside the Ark (A very impressive set, I might add.) where the last remnants of humanity lie slumbering. Of course, evil is afoot! A space-traveling race of Insects known as the Wirrn have gained entrance to the station and are planning to use humankind as food, absorbing all their knowledge at the same time.
This is a nice rubbermonster feast. The scenes of a human being converted into a Wirrn are excellent and the Wirrn themselves look groovy. As I mentioned before, the sets are really great and the action is fast and exciting. The actors seem to be having a lot of fun with their roles and, well, this is a must see. One could wish that all DW stories had this high quality. See it or be consumed by the Wirrn.
