Alex is a real person, born in Glasgow, who studied geology and engineering at the University of Edinburgh, fell in love with Andrea Cramond while there, and has continued their (open) relationship ever since. He is embittered by his betrayal of his working-class roots (he has become a manager and partner in his engineering firm), the Cold War, successive Thatcher governments, and the failure of his relationship under the pressure of Andrea's French lover's terminal illness. While returning from a sentimental reunion with an old friend in Fife, during which alcohol and cannabis are consumed, he becomes distracted by the power and beauty of the Forth Railway Bridge while driving on the neighbouring Forth Road Bridge and crashes his car. While in a coma in hospital, he relives his life up to the crash.
