Series 1

Two officers put their lives on the line as they try to talk down a man armed with knives; a police dog takes on a violent thug after their handler is attacked; and a 999 caller confesses to a murder.

An officer faces death during a search for a gunman; a raid on a gang ends in a rooftop chase; and an officer puts his life on the line as an inferno engulfs flats.

Following an assault, armed police chase down a suspect. Officers urgently need to capture a murder suspect, and a police officer is brutally attacked with a machete.

A criminal is on the run, a seemingly straight-forward stop and search puts a police man's life at risk, and two officers are confronted by a knife-wielding suspect.

Police break into a house to free a woman from a knife-wielding intruder, and find a fire starting to burn out of control. Plus an irate man decides to try and take on two female officers.

Police officers are caught up in a dangerous car chase with criminals in possession of a gun, and a no insurance stop reveals more than the officer bargained for.
