999: What's Your Emergency?

This episode focuses on an issue that is keeping the emergency services busier than ever: people's state of mind.

A quarter of the UK population will suffer from mental health problems at some time in their lives.

And with the number of psychiatric beds falling by 80% in a generation, inevitably the emergency services are dealing with more people with serious mental health problems.

PC Dave Donafee is called out to a Halloween party that's turned into a street fight and he comes face-to-face with one of his 'regular customers' who threatens to take on six policemen.

Paramedic Sue McGrath is called to a man with a history of faking injury. Tonight he's deliberately run into a taxi and he's previously thrown himself down the stairs.

Another regular caller, who claims to have taken 40 pills, requires an emergency motorcade to take him to hospital - a cry for help with a big price tag.

Meanwhile there's a race to come to the aid of PC Stuart Gornall when he's confronted by a man wielding a large knife.

And when a body is found outside a block of flats, having fallen from the 14th floor, all three emergency services are called. They must face a traumatic situation and piece together what's happened.

Is it the result of foul play, or the tragic result of someone losing the battle with their inner demons?
