In 1963, an old fashioned Police Call Box sat in a junk yard at 76 Totters Lane. An old man out and about exploring. A young girl wise beyond her years attending Coal Hill School. Two teachers become suspicious. Barbara and Ian suspect the girl is in trouble. They follow her home. The girl, Susan Foreman, vanishes into the junkyard. Barbara and Ian investigate. They discovered the Police Box. 'It's alive!' says Ian, he feels a faint vibration coming from within. The girl's grandfather returns. He confronts the two teachers, who accuse him of holding the girl inside the Police Box. They hear her call out to him from inside. Barbara and Ian push their way in and discover a world they never thought possible.
