Doctor Who: The Macra Terror

Directed by John Davies

With Patrick Troughton, Anneke Wills, Michael Craze, Frazer Hines and Peter Jeffrey

When the Second Doctor, Polly, Ben and Jamie visit a human colony that appears to be one big holiday camp, they think they have come across a truly happy place. Yet a shadowy presence soon makes them realise that the surface contentment is carefully controlled.
