Captains John Fellows and Henry Wynne-Walton finish their Army training at Sandhurst Military Academy and are sent to the Middle-East. John is to lead a parachute battalion while Henry is put in charge of a platoon of armoured cars of the Household Cavalry. John is constantly being told by his father, an ex-Guards officer that he is not as good as his brother who was killed during the war.

An American military officer and his wife move to a cottage in what they think is the peaceful English countryside, only to discover the area is a hotbed of spies and secret agents.

A young lady leaves her brutal husband and meets another man on board a ship.

It is pouring with rain at one minute to midnight on Friday the thirteenth, and the driver of a London bus is peering through his blurred windscreen as his vehicle sails down an empty road. Suddenly, lightning strikes, and a vast crane above topples into the path of the oncoming bus... Then Big Ben begins to wind backwards. Time recedes. And we discover the lives of all the passengers and the events that brought them to that late-night bus journey, from the con-man with a hundred-pound cheque to the businessman's distraught and elderly wife. Time flows on, inevitably, to the crash -- and past it, as some live and some die.
