A crash leaves an 18-year-old with a broken thigh bone; a man in his thirties suffers a heart attack; an elderly man is found at the bottom of the stairs.

A man is trapped in his car after a major accident; an elderly man falls off his roof; a cyclist needs urgent care after a collision with a car.

A critical care practitioner is dispatched to a double stabbing at a block of flats in Birmingham, and must prioritise which of the victims needs to be treated first.
