The BBC have release a selection of images from episode 5
“You only see the true face of the universe when it’s asking you for help.”
The Doctor, Bill and Nardole answer a distress call in deep space, and find themselves trapped on board space station Chasm Forge. All but four of the crew have been murdered – and the dead are still walking! In a future where oxygen is sold by the breath, and space suits are valued more highly than their occupants, the Tardis crew battle for survival against the darkest evil of all.
