The return of the documentary following the work of officers from Lincolnshire's Roads Policing Unit and the force's dog section. Barry Peach outsmarts a disqualified driver, handler Jon Peacock takes his new sniffer dog Jack to carry out a drugs warrant, Carl Warrener makes a jaw-dropping discovery when he pulls a car over in the early hours and Brian Conville gets mobbed when he deals with a reckless learner driver.

Barry hunts a lad wanted for assault, the police are hot on the tail of a suspected drug dealer and a drink driver tries everything to avoid giving a breath sample. Plus, Jon Peacock has a late-night encounter with two unusual lawbreakers.

Dan Brigginshaw is kept on his toes when a suspect does a runner, a routine vehicle check turns into a drug bust for Suzie Ranyard, and Barry Peach has his hands full when a group of Scottish revellers clash with bouncers in Skegness. Elsewhere, Jim Woolerton and Jason Baxter catch out a rookie rider who is breaking the law.

A foul-mouthed pensioner pushes Barry's patience to the limit, Sarah gives a bad-boy biker an early birthday present and Jim's Audi S3 is outclassed by a car 30 years its senior. Plus, Mike is left open-mouthed when he encounters a drink-driver who is three times over the limit.

Jim intercepts a car containing cannabis, a late-night reveller talks himself into trouble and Sgt Baxter has his work cut out when confronted by a dishonest driver. Plus, young drivers get a crash course in how to deal with skids at a training session run by the unit at RAF Scampton.

Officers are forced to exercise caution when they stop an uninsured driver who is known to have a violent past, while Jon Peacock and police dog Brad are on the hunt for suspected burglars.

The hunt for a suspected burglar takes an unexpected turn, a late-night stop reveals a bag of drugs, Jon Peacock has a tussle with a fallen tree and Barry Peach deals with a case of some very hot dogs locked inside a car.
