The year is 1989. In London, safecracker Raine Creevy breaks into a house - and finds more than the family jewels. In the Middle East, the kingdom of Sayf Udeen is being terrorised by Soviet invaders and alien monsters. And on the Scottish border, a highly guarded facility contains an advanced alien weapon. All are part of the Doctor's masterplan.
