Summary: Something has gone seriously wrong with 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. A rescue mission recovers something, but whatever it is, it certainly isn't human. To find out what has happened to the astronauts, the Doctor must head into space without the TARDIS.
