Advanced Nurse Practitioner Cheryl Barnes has a serious trauma case to look after when 59-year-old Derek arrives with possible serious internal injuries after the car he was working on collapsed onto his chest. Elsewhere, a 47-year-old man is rushed in resus struggling to breathe with a collapsed lung, and a keen gardener arrives with an agonising back injury.

It s been a busy night at Barnsley Hospital's casualty department, so when Sister Benita Wainwright arrives to head the shift, the corridors are already packed full of patients.
