On the hottest night of the year, two trains enter the Channel Tunnel one bound for London and the other Paris. Passengers include a Eurosceptic MP, a man on a mission, a mini bus on a stag weekend and some passengers trying to travel incognito. They will never reach their destination. Mid-way, the trains are stopped and taken over by terrorists who are going to hold every passenger hostage - giving them fifteen minutes of fame on the ultimate reality show streamed live all over the world. If the world pays your ransom you live - if it doesn't - you die.
