On a country road out the back of beyond, a couple in their 40s are driving home from a party. Its 2am and pitch black. Suddenly high bright lights flash onto the windscreen. They hit the brakes, but it is too late. Their car crunches and buckles in the full-speed, head-on collision. The crash wakes a couple in a nearby farm house, who call 111. But when the limited country emergency services arrive they can find no trace of the other vehicle involved in the crash – no broken glass, no evidence that it exists.
Elaine, a young paramedic, can find thready pulses for the husband and wife in the car. The local police chief and country fire fighters work to free the victims, the beams from their vehicles’ headlights their only source of light.
Then one of the firemen feels a force and is thrown into the side of the car. The others tell him to stop messing around. He tries to explain there’s something out there, but they’re not listening.
However, when their backs are turned and the husband in the car vanishes into thin air, they realise this is no regular accident. And that they are not alone.
They soon find themselves the victims of a something or someone in the darkness. They are trained for every emergency imaginable – but this is beyond that. As scared as she is, Elaine can’t forget that she is there to do a job – to save the woman still trapped in the car. She has seen so much needless death and lost so many victims since starting her job a couple of years ago, she cannot face losing another one. No matter what, she is going to save this woman.
The emergency workers battle the darkness, and themselves, whilst cutting the woman free. Many will die tonight, and Elaine must learn that not everyone can, or should, be saved.
