At Queen's Medical Centre, Nottingham - one of the busiest A&E departments in Europe - the staff are in shock when their much-loved colleague, 55-year-old Sister Lou, is rushed in after being knocked off her bike. Lou's colleagues and close friends are concerned that she may have serious internal bleeding as well as severe injuries to her shoulder and wrist. Stuart, who's 57, has fallen from a six-foot ladder, severely fracturing and dislocating his ankle. Previously, Stuart had mental health issues while working as a security guard, which led him to change direction in life.
