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.

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 is a 1984 children's television drama based on the 1968 novel by John Wyndham and was broadcast on ITV in the United Kingdom. Two sequels were produced. All were written by Anthony Read and produced by Thames Television. The series was also broadcast and popular in Czechoslovakia - both dubbings were made. While the 1968 novel was set in an unspecified 'near future', the TV adaptation was set contemporaneously in the mid-1980s. The Gore family acquire a second generation Citroen CX car which was marketed as being technologically advanced at the time.

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.
