When a passenger realises that someone is attempting to hack his train, he makes a desperate call for help. But can two total strangers work together to get everyone off in time?
Whilst a desperate Joe considers going to extreme lengths to leave the sleeper, an under-fire Abby starts to realise that she has as many obstacles in her path as the train does.
Set on a sleeper train traveling from Glasgow to London, a government agency desperately tries to intervene in the rapidly-escalating events onboard. Can two people who've never met, one on the train and one not, work together to save the lives of its disparate group of passengers as the Heart of Britain service hurtles towards what might quite literally be its final destination?
