In the control room, the firefighters are busy taking all kinds of emergency calls from around the Dublin region. When Dublin Fire and Rescue's advanced paramedics are sent to a Dublin hostel to try to revive a young man whose heart has stopped after a drug overdose, their training is key to his survival. Every second is crucial if he's going to survive, and while the ambulance is on the way, the control room operator talks the emergency caller through CPR and operating the defibrillator. Another call comes in and several fire engines are dispatched to a well-known Dublin bar. A major fire is spreading across its roof and threatens to burn the whole building. On another watch across town, the firefighters are called into action when a chip pan fire goes out of control and engulfs an apartment. And an elderly man is treated by Dublin Fire and Rescue's paramedics after a vicious assault.
