Friday the Thirteenth

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 windshield 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 of 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 businessmans distraught and elderly wife. Time flows on, inevitably, to the crash, and past it, as some live and some die.
