Asher and Michaela, who are law students, attend a law social at the start of the academic year. They both consume several alcoholic drinks. Asher offers to give Michaela a lift back to her flat. Michaela has seen the amount of alcohol consumed by Barry and is initially reluctant but, since it is late and raining heavily, she accepts.

On the way to Michaela's flat, Asher loses control of the car, which skids and mounts the pavement, slamming into a wall.

Michaela who is not wearing a seat belt, is very seriously injured. Asher is unhurt. Wes, a passer-by, is cut by flying glass from the collision and, being a haemophiliac, bleeds to death. His pregnant girlfriend, Laurel is called to the scene of the accident. She reaches there after Wes' body has been removed, but is so overcome by the sight of blood that she suffers psychiatric injury and consequently miscarries.
