The space race has been dominated for decades by two rival superpowers, but just when they thought they were alone, a new force has arrived. Britain has developed an amazing space exploration buggy that might solve the planets energy problems. But will Britain's greatest achievement become one conman's finest hour? Will Spencer and his right hand man/master of disguise will re-unite alongside Will's niece Fiona head of marketing at the British Space Centre, and Travis, Tom's accident-prone son, in a series of comical misadventures spanning across the United Kingdom and beyond! In this fun family movie, our unlikely heroes will create a plan--the likes of which the world has never before seen--to steal what every government wants. And, the only person that stands in their way is Scotland Yard's worst detective. Together they will use the UK's highly developed space technology to outsmart the world's most powerful ambassadors and ultimately help put the 'Great' back into Great Britain.
