Nightsleeper - All Seasons

Nightsleeper is a thriller in which a train is 'hackjacked' while travelling from Glasgow to London, and suddenly finds itself on an uncertain journey with an even less certain destination. Part fast-moving heart-in-the-mouth action-adventure and part twisty-turny whodunnit detective story, it's a roller coaster ride set across a single night where no-one is ever quite who they seem.

Leading the fight are Joe Roag, an off-duty police officer who is a passenger on the train, and Abby Aysgarth, the acting technical director at the National Cyber Security Centre (NCSC). To stop the train, they'll have to work out exactly who's behind this. But are they fighting a hostile state, a terrorist organisation, or organised crime? Who is the self-styled 'Driver' who seems to be one step ahead of their every solution?

As Abby and Joe - who have never met in person - try to establish a bond that will withstand everything the night throws at them, will Joe's fellow passengers help or hinder their desperate efforts? Could one of them even be involved? Who can Abby and Joe really trust?

This time the action moves from the rails to the open water, as a new high-stakes thriller unfolds aboard a ship travelling across the Irish Sea - and behind every cabin door is another story, another surprise... The passengers and crew on tonight's Belfast to Liverpool passenger ferry are about to experience six hours of non-stop thrills and spills, secrets and lies, triumphs and tragedies. None of them are quite as they seem. Nothing in their lives will ever be the same again. Not all of them will make it to the other side.
