Two people who have never met must work together to foil a cyberterrorist plot on a highspeed train in BBC1's Nightsleeper.

Set in real time, the six-part story begins when off-duty cop Joe Roag (The Ipcress File's Joe Cole) takes his seat on the Heart of Britain, an overnight train travelling from Glasgow to London. But before he and his fellow passengers can get themselves comfortable, the service is hijacked by a dangerous group of hackers who are effectively holding them hostage as the train hurtles down the country.

As panic spreads through the carriages, Joe is horrified when he unearths evidence that someone on board might be in league with the terrorists.
