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?

Realising that someone onboard may be working with the hackers, Joe turns his attention to his fellow passengers, whilst Abby stuns her colleagues by taking the train off the mainline.

As Hud and Miller interrogate Abby, Joe tries to deal with the fallout to the shock shooting whilst deciding whether or not to put his faith in Saj or the other passengers.
