Dr. Who

Dr Who was an eccentric human scientist, living in a cottage in England with his granddaughters Susan and Barbara. He also had a niece named Louise.

Dr. Who had invented time travel in the form of Tardis, a space-time machine, the exterior of which looked like a police box.

When Barbara's boyfriend Ian Chesterton was visiting his house, he, Susan and Barbara went to have a look at Tardis. Ian accidentally pulled a lever and the four of them were transported to Skaro, the home planet of the Daleks.

Dr. Who, Susan, Louise and a police constable named Tom Campbell later travelled to London in 2150 and found that it had been devastated by a Dalek invasion years earlier. Once there, the four of them assisted in freeing Earth from Dalek occupation.
