The BBC's hit thriller Nightsleeper is returning with a second outing – but this time, the likes of Colin Morgan and Sally Lindsay are leading the cast.
The original run, which aired in 2024, followed a Glasgow-to-London sleeper train hijacked in a cyber attack, which forced two strangers – played by Peaky Blinders actor Joe Cole and Lazarus star Alexandra Roach – to work together to save its passengers.

But as the tide turns, secrets surface and fear floods the decks; it isn't long before those on land are all at sea too."
Lindsay Salt, Director of BBC Drama, described the thriller as a "brilliantly gripping story," adding, "With danger lurking beneath the surface at every turn, viewers are in for a truly nail-biting journey."
