The original 1967 master recordings of 'The Macra Terror' were lost soon after the programme's original transmission. However, audio-only recordings have survived and have been used here to create a brand new fully animated reconstruction of this lost classic. With highly detailed hand-drawn animation carefully lip-synced with the original 1967 audio, this new production allows viewers to once again experience this Doctor Who chiller in full. The Doctor (Patrick Troughton) and his companions (Jamie, Polly and Ben) arrive on a human colony in the far flung future. The colony outwardly appears to be happy and carefree. But behind it's cheerful exterior the colony has been secretly infiltrated by a race of giant parasitic crab creatures called the Macra. The Macra brainwash the human colonists to mine toxic gas in the levels below the colony. Ruling the colony from a control centre in the heart of the main city they scuttle down to the city at night looking for food. The Doctor's friend Ben is soon taken over by the Macra and under their malign influence, he turns against the Doctor. As more colonists are picked off in the night and as their influence spreads, the Doctor sets out to bring an end to the Macra terror.
