A fire alarm goes off and Sister Benita must prepare the entire department - staff and emergency patients - for a full evacuation, while paramedics rush in 32-year-old Owen after his car was involved in a head-on collision with a 20-tonbin lorry. A woman needs an emergency operation to remove a blood clot and a man's 87-year streak of not needing hospital care ends.

A high number of call-outs for ambulances has resulted in paramedics queuing with patients in the corridor at Barnsley Hospital's A&E department, so the team must decide who is seen at once and who can wait. Priority is being given to two patients fighting for breath, with junior doctor Emma Faragher treating 72-year-old Lynda and Dr Chris Lamare attending to two-year-old Seb.
