The action this time takes place on Earth, with the Doctor (Jon Pertwee) coming up against all kinds of opposition within the British space program when he attempts to investigate some mysterious messages travelling to and from the returning spaceship Mars Probe 7.

With no contact from the astronauts since the rocket started its return journey from Mars, Space Control is now extremely worried about the fate of the crew.
