The BBC has released two first-look images from its upcoming real-time thriller ‘Nightsleeper.’

The story is about the hacking of a sleeper train travelling from Glasgow to London, and a government agency’s frantic efforts to intervene in the rapidly-escalating events onboard. Can two people who’ve never met, one on the train and one not, work together to save the lives of its disparate group of passengers as the Heart of Britain overnight service hurtles towards what might quite literally be its final destination?

Alexandra Roach (The Light in the Hall) and Joe Cole (Gangs of London) lead the cast of the suspense thriller, written by BAFTA award-winning writer Nick Leather (Murdered For Being Different) from Fremantle’s Euston Films, coming to BBC One and BBC iPlayer in early 2024.
