Overview: All too often young men are admitted to the Walton's critical care unit as a result of horrific road accidents. Jimmy, aged just 21, is the latest of them. He is in a coma following a car crash. The extent of his brain injury is unknown, but an operation is needed urgently, as his brain pressure is rising to dangerous levels. Another patient, Michael, collided with a fellow player during a football game and the accident brought on a seizure. At the Walton, he is diagnosed with a brain tumour which needs immediate surgery. The accident has changed Michael's whole life within a single day. This hard-working father will not be able to drive, and therefore work, for months. It's a shock on many levels – not least for his partner, Sam, mother of their five children.
