The BBC has unveiled the initial images from Nightsleeper, its upcoming real-time thriller centred around the hacking of a sleeper train journeying from Glasgow to London. The series portrays a government agency’s frantic attempts to intervene in the swiftly escalating events onboard. Can two strangers, one aboard the train and one elsewhere, collaborate to safeguard the diverse group of passengers hurtling towards what could indeed be the Heart of Britain overnight service’s ultimate destination?

Leading the cast of this suspenseful thriller are Alexandra Roach (The Light in the Hall) and Joe Cole (Gangs of London). The script, crafted by BAFTA award-winning writer Nick Leather (Murdered For Being Different), originates from Fremantle’s Euston Films and is scheduled for release on BBC One and BBC iPlayer in early 2024.

In the series, Alexandra assumes the role of Abby Aysgarth, the Acting Technical Director at the UK’s National Cyber Security Centre. Abby, on the verge of a well-deserved vacation, receives a phone call that shatters her plans— the UK railway network is under attack. Joe Cole plays Joe Roag, an off-duty cop onboard, anticipating a peaceful night. However, over the next six tumultuous hours, Joe’s tranquility is shattered as he and Abby confront both their own distrust and the unpredictable actions of the individuals now in control. Their shared mission is to prevent the Heart of Britain from reaching its final destination, in more ways than one.

The stellar cast also includes Alex Ferns (The Devil’s Hour), Sharon Small (The Bay), James Cosmo (Tom Clancy’s Jack Ryan), David Threlfall (Shameless), Daniel Cahill (The Control Room), Lois Chimimba (Vigil), Gabriel Howell (The Fence), Katie Leung (Harry Potter), Leah MacRae (Rosie Molloy Gives Up Everything), Ruth Madeley (Years and Years), Adam Mitchell (Mother’s Day), Pamela Nomvete (Andor), Scott Reid (Maxine), Sharon Rooney (Barbie), and Parth Thakerar (Gangs of London).
