Competition winner Mrs Noah is being given a tour of Britain's latest space station, The Britanna Seven, when she and several of her luckless companions are accidentally launched into space.
Stranded Mrs Noah and her companions try to get used to life in space as ground control tries to bring them back home.
Britain's space shuttle is launched to rescue Mrs Noah and her companions from the Britanna Seven, however, before the shuttle can dock a means must be devised to seal the airlock.
The space shuttle's ballast tank gets damaged making it impossible for the shuttle to return everyone to Earth.
Mrs Noah decides that they should all settle down in the crew quarters since it looks like they won't be rescued for some time.
Ground control comes up with a plan to bring the Britannia Seven closer to the Earth, slow the space station down and individually eject its unfortunate and reluctant passengers.
