Matthew Gore was adopted at birth. He has his 12th birthday today. While he is struggling in Math class, a mysterious bluish green mist comes through the window and enters his head. Suddenly, Matthew can solve complicated math problems, and hears a voice in his head telling him the answers to the test.

Matthew's father and mother, David and Mary, notice him talking to himself and asking very complicated questions they cannot answer. His sister Polly has an imaginary friend and they think Matthew has one too, even though he is a bit old for that. He seems to spend a lot of time drawing in his room, which he never did before.

When Matthew sees the new car David has bought, he starts throwing a tantrum. Polly runs to get her parents and Matthew starts saying "Chocky" doesn't like the car. They decide to invite their psychiatrist friend Roy over for dinner to have an informal chat with Matthew. After talking to him, Roy believes Matthew is possessed by someone named Chocky, but not of this earth.

Matthew asks Chocky to appear to him, but Chocky can only show her light energy. She explains that seeing her will only frighten him. His mother Mary finds artwork in his room that is much too complicated for a twelve year old. They ask him about it and he says that is the way Chocky sees things.

Matthew is becoming more unstable as he is having outbursts of arguments with Chocky. David and Mary soon realize that it is a real voice from an alien planet who has been talking to Matthew. Soon, the government is interested in this alien life force and want to investigate.

Fear spreads when Matthew goes missing from school, panic sets in when a witness comes forward, stating he'd seen him getting into a stranger's car.
