When the TARDIS jumps a time track and the Doctor and his companions get an unpleasant vision of themselves as installations on a colonizer's museum planet, the crew must unite with the world's oppressed native population to avert this potential future. Special guests RAY BENDER -- dressed as the 11th Doctor -- and PATRICIA MILLER -- playing River Song -- join host Jessica Greenwell to talk museums in Doctor Who, British culture, and how television's longest running science fiction show found its voice.
