The return of the documentary following Derbyshire police on duty between 9pm and 10pm, beginning as officers prepare to raid the address of a suspected drug dealer with links to an organised crime group. At Comms HQ it is a hectic night and at 9.10pm a woman calls 999 reporting that her brother is threatening to slit his wrists.

Police arrest a woman who is on a rampage with a hammer, but when another family member turns up and starts abusing officers, they are faced with a potentially violent situation. Meanwhile, a chilling call comes in from a supermarket as a shopper is spotted browsing the aisles with an eight-inch knife in his back pocket.
