C093 The Invisible Enemy

It'll take more than an anti-body pillow fight to defeat the universe-threatening ejaculate of a megalomaniac space shrimp * * * The Fourth Doctor and his companion Leela are drawn into a fight for the future of mankind when a sentient space virus called The Swarm begins to infect human settlers on Titan and a nearby hospital asteroid. Led by the Nucleus, The Swarm is intent on taking over humanoid species and ultimately achieving galactic domination. The Swarm even infects The Doctor, though, implanting inside his brain the Nucleus itself, and now Doc and Leela, while backed up by their new best friend, K-9, must clone themselves and Fantastic Voyage into his noggin. * * * Check out WHOBACKWHEN.COM for more information, Doctor Who TV Serial and Audiobook reviews, ratings and ramblings, and loads more podcast episodes.
