The complete series of the sci-fi comedy drama from acclaimed 'Quatermass' writer Nigel Kneale. Des Kinvig (Tony Haygarth) is an ordinary electrical repair man and UFO spotter, whose life is radically changed when he meets the beautiful Miss Griffin (Prunella Gee). She turns out to be an emissary from the planet Mercury, and recruits Des to help in an ongoing galactic war against the dreaded ant-like Xux creatures, who have Earth in their sights. But are Kinvig's intergalactic adventures real, or just the product of an overactive imagination? Episodes are: 'Contact'; 'Creature of Xux'; 'Double, Double'; 'The Big Benders'; 'Where Are You Mis Griffin?'; 'The Humanoid Factory'; and 'The Mystery of Netta'.
