The fifth episode of Chocky airs on Thames Television, adapting the novels of John Wyndham into a television serial starring Andrew Ellams and James Hazeldine. 
Matthew manages to save his younger sister and gets her to dry land, to the astonishment of his father, who points out that Matthew has never learned how to swim. It quickly becomes apparent that Chocky has returned, and is responsible for Matthew suddenly being able to swim proficiently. BBC Radio interviews Matthew, who opens up – to his parents’ alarm – about hearing a voice that told him how to swim; the story also makes the papers. More reporters, and self-proclaimed psychics and witches, descend upon the Gore household, to his mother’s alarm. Dr. Landis arranges for Matthew to spend time with a hypnotist; after this session, Chocky abruptly leaves Matthew, instructing him to forget her.
