Sky is a mystically-oriented children's science fantasy television serial made for ITV by HTV in 1975 and broadcast in six parts.
Looking something like a young, effete blond ubermensch, a morally ambiguous alien boy with weird solid blue eyes, the eponymous Sky (Marc Harrison), finds himself on Earth, where he uses his psychic powers for achieve his goal of ensuring a way back home. Sky finds the very world soul of Earth, in the form of nature, rejecting him, the way an immune system might an infection. In his quest to return home, he interlinks his own destiny with that of three human children. The serial was written by Bob Baker and Dave Martin, also known for their scripts for Doctor Who and a fantasy television series for children, Into the Labyrinth.
Although the series was kept on 2" videotape into the 1990s, during a transfer to film stock episodes 3 and 7 were damaged beyond repair.
The series was finally released by Network DVD in May 2009, with the damaged segments replaced by inferior, but watchable, VHS copies of the episodes.
