Nightsleeper (season 1)

On a sleeper train traveling from Glasgow to London, a government agency is desperate to intervene in the rapidly unfolding events on board. The Heart of Britain train feels as if it has been hacked into, it has become unmanageable and is now hurtling towards what could literally be its final destination. Joe Rogue, a police officer on duty on the train, and Abby Eisgart, acting technical director of the National Cyber Security Center, who communicates with Rogue remotely, are two people who previously didn't know each other but must now work together to try to save the lives of the passengers. To stop the train, Joe and Abby will have to figure out who exactly is behind this (a hostile state, a terrorist organization, or organized crime) and which of the passengers can really be trusted, and who might be involved in the sabotage. Who is this self-appointed Driver who seems to be one step ahead of every decision?rn
