It's the last Saturday night before Christmas and it was always going to be a busy night for the service, with controller Sui having to prioritise stabbing victims and reports of drowning over patients like Betty, whose daughter says she's fine but needs help getting her up having fallen to the floor.

This episode follows West Midlands Ambulance Service over three shifts in Staffordshire, where crews are dealing with an increasing number of social issues, drug and alcohol misuse, and mental health patients.
