The show starred William Hartnell as the Doctor. In this scene, 20th century schoolteachers Ian Chesterton and Barbara Wright have followed enigmatic student Susan Foreman home from school, concerned about her odd behaviour. They discover she appears to live in a junkyard, and they confront Susan's mysterious grandfather about her whereabouts, eventually discovering more than they bargained for.
It's a very different show from the modern version, with Hartnell playing a much more mysterious and somewhat sinister figure. From here of course, he shanghais Ian and Barbara on a journey through time and space, starting off 50 years of amazing adventures!
