Join The Second Doctor (Patrick Troughton) on an intergalactic rescue mission to save an enslaved human mining colony from scuttling, crab-like Macra monsters and giant swarming insects, deep under the surface of a distant future planet.  The Doctor and his companions—Ben, Polly and Jamie—must outwit the planet’s evil Pilot or fall victim to poison gas, brainwashing, hypnotism and deadly explosions.  Climb aboard the TARDIS for all four amazing, formerly lost episodes—recreated for your sci-fi pleasure by combining brand-new animation with the original recordings.  From BBC Studios.  4 episodes. 1 3/4 hours on 2 discs.
