The new series of 999: What's Your Emergency? focuses on the work of police and paramedics in Cheshire. It follows incidents from the moment when a 999 call is made, to the arrival of the frontline police and paramedics: the hard-working men and women who protect us from ourselves and each other while seeing us as we really are. They talk with honesty and wit about the increasing challenges of modern Britain. With alcohol-related incidents in the UK costing the emergency services nearly £3 billion a year, this episode features people who risk ruining their own - and other people's - lives for the sake of a night out.
