Chocky was subsequently repeated in a re-edited single episode on 31 December 1984, with a similar single-episode edit repeat of ''Chocky's Children'' following on 27 December 1985.
Chocky Matthew Gore is an intelligent boy chosen by a mysterious
extraterrestrial visitor to be a source of information about life on
Earth. As his schoolwork and artistic talent improve dramatically he arouses the suspicion of powerful groups who wish to tap into the amazing fund of knowledge to which he is now party.
''Chocky's Children'' A year has passed since Matthew said goodbye to his alien friend, and in the summer holidays he meets Albertine, a mathematical prodigy, with whom he discovers he can communicate
telepathically. One day Chocky returns to warn Matthew that they are both in danger. When he returns to tell Albertine, he finds she has disappeared.
''Chocky's Challenge'' Chocky hopes, with Matthew and Albertine's help, to help the human race discover cosmic power, which unlike Earth's finite natural resources, will sustain them for as long as the universe itself exists. But their knowledge has aroused a great deal of interest from the military, and they are willing to take drastic action if they don't get what they want. == Cast ==
