Clara’s back in the TARDIS (we knew she wouldn’t be able to stay away for long!) as Series 8 of Doctor Who continues next weekend.

In Flatline by Jamie Mathieson, the impossible girl is separated from the Doctor and discovers a new menace from another dimension. But how do you hide when even the walls are no protection?

With people to save and the Doctor trapped, Clara goes against an enemy that exists beyond human perception.

Directed by Douglas Mackinnon, Flatline airs on Saturday 18th October at the slightly earlier time of 8:25pm on BBC One.
