Called to an old hanging post after a man thought to be drink driving, two officers end up fighting for their lives. A suspect bites a police dog and attacks his handler, and a traffic officer is dragged into a busy road by a violent motorist.

PC Mark steps in front of a car to ask the driver to stop, but the driver uses his car as a weapon. A criminal in handcuffs steals a police car to use as a getaway vehicle, with the officer still inside it.

After a knife falls out of a criminal's pocket in Bedford, it takes three officers to get him in cuffs. Meanwhile, a local bobby is knocked out cold after a pub-goer launches an unprovoked attack.

PCs Ben, Launa and Rafal thought they were attending a simple case of neighbours arguing, but the emergency call was a trap to lure the officers to an attacker's door. Meanwhile, PC Carroll happens across a street mugging.
