Protect and Survive (audio drama)

Protect and Survive is a Big Finish Productions audio drama based on the long-running British science fiction television series Doctor Who. It was released on CD and download in July 2012, and was first broadcast on BBC Radio 4 Extra on 17 November 2013 as part of the Doctor Who 50th-anniversary celebrations.

Plot
The Doctor has disappeared, and the TARDIS is out of control. Ace and Hex find themselves marooned on Earth in the 1980s at the height of the Cold War.

Cast

 * Seventh Doctor – Sylvester McCoy
 * Ace – Sophie Aldred
 * Hex – Philip Olivier
 * Albert Marsden – Ian Hogg
 * Peggy Marsden – Elizabeth Bennett
 * Moloch / Patrick Allen (announcer) – Peter Egan

Continuity

 * The exterior of the TARDIS was rendered white during the events of The Angel of Scutari. It remained as such for the previous trilogy of stories, Project: Destiny, A Death in the Family and Lurkers at Sunlight's Edge.
 * The TARDIS with the black exterior was inexplicably seen in a trilogy of solo Seventh Doctor stories, Robophobia, The Doomsday Quatrain and House of Blue Fire, which, for the Doctor, take place between Lurkers at Sunlight's Edge and Protect and Survive.  It is also in Project: Nirvana, which takes place just before Protect and Survive.
 * Peggy Marsden returns in Gods and Monsters.

Critical reception
Doctor Who Magazine reviewer Matt Michael strongly praised the play, noting that it was "one of the bleakest" made by Big Finish.
