A science-fiction thriller in seven episodes by Fred Hoyle and John Elliot.
Starring Esmond Knight and Mary Morris
with Peter Halliday, Patricia Kneale and Noel Johnson
and introducing Julie Christie

With the help of a computer designed from a message from outer space, Professor Dawnay succeeds in making and keeping alive a synthesised creature, and even makes it grow. The computer achieves a haphazard and unsatisfactory communication with the creature. Against his better judgment, Fleming, who built the computer, suggests arranging a direct electrical supply between it and the machine. Even this is not entirely satisfactory, and the computer, in an attempt to extend its knowledge of humanity, compels Christine, one of Professor Dawnay's assistants, to take hold of the exposed terminals, and kills her.
