"Turn Left" is the eleventh episode of the fourth series of British science fiction television series Doctor Who. It was written by showrunner Russell T Davies and broadcast on BBC One on 21 June 2008.
Rocco Colasanto (Joseph Long, far left), along with his family and other foreign citizens, is taken to an internment camp in the midst of the dystopia caused by the Doctor's absence. Colosanto's internment was written as a direct parallel to the Holocaust and was positively reviewed by critics for the episode's depiction of dystopia.
