Sky is a mystically oriented children's science fantasy television serial made for ITV by HTV and broadcast in seven parts from 7 April to 19 May 1975.

[1] A mysterious alien boy with strange solid blue eyes, the eponymous Sky (Marc Harrison), finds himself on Earth in the wrong period of time.

He uses his psychic powers to achieve his goal of finding a way to his correct temporal destination, which is after "The Chaos".

Sky is confronted by the world soul of Earth in the form of Nature, which tries to reject him much as an immune system might an infection.

The series was finally released by Network Distributing Home Entertainment/Granada Ventures Ltd in May 2009, with the damaged segments replaced by inferior, but watchable, VHS copies of the episodes.
