Nightsleeper is a real-time thriller 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. In the UK, where the series premiered on the BCC, the first episode attracted 8.5 million viewers (28-day figure), making it one of the UK's most-watched dramas of the year.
