A futuristic theme park is devoted to Margaret Thatcher. Actors and Spitting Image puppets are combined for the first time on British television. The Jenkins family are selected by computer to be the first visitors to `Thatcherworld'. They journey through Grantham in the 1920s to the artificial world of the 1980s. Along the way they meet the significant players and events in Margaret Thatcher's life - her father, husband, Ted Heath, the Saatchi brothers, Geoffery Howe, Michael Heseletine and John Major.
