Sky (1975)

Eerie, unsettling and a benchmark production for children's television in the 1970s, Sky was created as one of the run of outstanding children's dramas HTV produced in that decade. Filmed in such richly atmospheric locations as Avebury, Glastonbury Tor and Stonehenge, Sky is a mixture of ecological fable, science fantasy and good, old-fashioned peril.

Marc Harrison stars as Sky - an ethereal boy who materialises on an Earth that is as unprepared for him as he is for it. He soon realises that he's been brought to the wrong time and must seek out the Juganet to return to his correct place in reality. With the help of tearaway Arby Vennor, his sister Jane and friend Roy, he must race against time as Nature rejects Sky and the Earth's immune system creates the evil Goodchild, who is out to stop him at all costs...
