PCs Jamie Leslie and Jan Simlesa are teamed up in North Tyneside when they spot a shifty driver in a car worse for wear. As the vehicle turns into a cul-de-sac they hit the blues and twos but the driver has no plans to come quietly. Caught in a dead end, he rams the police car, sparking a high speed pursuit. The driver finally sees sense and stops, but he's short tempered and, even worse, stinks of booze. When a roadside breath test is suggested, he makes his true feelings known.
In Sunderland, PC Mary-Ann Hutchison's cop car appears to spook an Audi driver into a last-minute turn and anear miss. Thinking he has something to hide, Mary-Anne gets on his tail. He looks to have got away, until another motorway cop car gets behind the suspect in the city centre. Seeing the net closing in, the driver ditches the car and runs into a building site. But there's nowhere to hide with the police chopper on the case. When the cops on the ground catch up, the man reminds Mary-Anne they went to the same school!
Later, Jan and Jamie are called to support their sergeant in solving a roadside mystery. A driver is on trade plates, claiming to be on a test drive. The only problem is, it's the middle of the night and the test drive has been up and down the country! Matters aren't helped, when Jamie tries to get to the truth and the driver changes his story not once or twice, but three times. Will Jamie manage to work out what's fact and what's fiction?
