A workplace accident leaves a man with a laceration exposing his rib cage, and the critical care team respond to reports of a group of women being attacked with machetes.

In this episode, a man is fighting for his life after a cardiac arrest. Labourer Aaron was attacked outside his home, and the 32-year-old has been stabbed in the neck and abdomen. A gunman is reported to be on the loose at a crowded house party. With reports of at least one person dead, Dr Richard Fawcett and critical care paramedic Dan Fletcher are dispatched. When 12-year-old Benjamin was cycling home from school, he collided with a car and was thrown against the windscreen.
