Steve is in Exeter, heading out to help with the hunt for a man behind the wheel of a reportedly stolen car being driven by a man also suspected of stealing numberplates. The car is, as feared, abandoned – on the edge of a country park, so it's going to be down to Razor now. The doughty hound immediately picks up a track, and pulls Steve on a merry cross country chase through bushes until they catch up with someone out in the middle of nowhere. The man refuses to get on the ground, but when finally floored, he starts hurling threats of complaints around because his bluetooth headset's fallen off. While Razor enjoys a good drink for his efforts, the collected officers go to search the car, only to find that the keys are missing. Out comes Razor again. He has a reputation within the dog section for being able to find proverbial needles in haystacks – and that's exactly what he does. One set of keys comin' up!

Out in Plymouth with Roger and Mike on the hunt for illegal drug activity. Jim, out on the road with Mark, has pulled a car with four people in it, suspicious that there might be drugs on board, so he needs some back up. All four occupants corralled, they head back to the nick for the requisite searches. Things are reasonably congenial at first, and people seem happy enough – particularly as nothing's been found. Yet. Jim does find some coke – but as it's the fizzy rather than sniffy kind, that's not much use to them. A search of the female passenger uncovers a small portion of white powder in her handbag which is thought to be amphetamine, and the mood changes amongst the others as more information about them becomes available, particularly as one of them appears to be wanted for abandoning a taxi without paying – and not bothering to answer for it at court. Not to mention a teensy-weensy bit of ketamine which is – nonetheless – enough to have its owner hauled into the custody suite. Only one of the four turns out to have nothing hidden or outstanding.

It's TAG time and the crew are in Tiverton prepping for a raid, and motivation at such an early hour is offered in the form of pasties once the job is done. There's information that their target house will reveal two women in possession of a stash of heroin due to be sold on the streets. The door gives in one go under the enforcer, and the occupants are taken completely by surprise. The three are cuffed prior to the search of the cluttered property. Simon finds that two of them were in the process of shooting up in the kitchen, having used one of around forty wraps of heroin crammed into a kinder egg case. Heading back for their pasties, they are interrupted by another job elsewhere to find another dealer nearby. Off they go again, charging upstairs to another flat where they disturb one of the occupants, a mother. Her daughter is out, which is unfortunate, but the search begins as Tony attempts to calm the woman down. Her claims that they've made a mistake is immediately refuted by the discovery of some cannabis, before coming across a hidden bag of powder which could be amphetamine, accompanying some more cannabis and a rather implausibly large amount of cash. An arrest follows, by which time the daughter has come home and is picked up too. And finally the TAG get their pasties...

Steve is right on the edge of the force area, attending a rather unpleasant incident in Wellington involving a man who has threatened to kill his wife and son with an axe. Tasers have been authorised, and Steve is on hand to get Razor on the case if the man flees. The wife and son are not at the address – being safe elsewhere – but the man has vowed that he will hunt them down. The house he's living at seems to be empty, but the need to find him is too pressing for them to leave. Eventually, they feel they can't stay any longer; but, as they leave, one of the officers finds a massive axe in the man's car. That settles it. They're not leaving now. Out comes the enforcer, as there is every possibility that the man is just ignoring them. He is. As the door goes in, he can be seen looking out of an upstairs window. Numbers, however, win out, and there is no resistance as he is led away from the property.

Taff and Mark are lurking on a Bridge over the M5 in the Black ST, looking for dangerous drivers. They head off after a car which has zipped down the motorway; and Taff is having a bit of a job getting after it. Even as he speeds up to over 100 mph, the car is still leaving them behind – even getting up to 110 they're neither gaining nor dropping. Finally, however, they get behind it and Mark does the honours with the gesture, and some genial discussions with the occupants. As he does so, Taff – still in the ST calling in the details – spots one of the rear tyres is bald. Details sorted, Taff joins Mark and calls the driver over to look at the tyre before getting him into the ST and discussing the matter while Mark sorts out the amount of wear on the rogue tyre. In doing so, he finds another that's been worn down to illegal proportions. The driver is allowed on his way – to a garage to get new tyres.

Lunchtime in Tiverton (Best Market Town 2003!). Mike is with Chris heading down the M5 to follow up a call about a suspected drunk lorry driver. The lorry was spotted at Taunton Deane, with the driver and passenger apparently imbibing from cans of something booze-like. They catch up and pull the lorry over, and off Chris goes to talk to the driver, who is popped into the back of the car for discussions as there's a potential insurance problem as well. There's no immediate smell of alcohol, though there are a couple of bottles in the cab, one of which the passenger's been pegging at, though he admits the driver did have a swig or so before leaving their previous job in Taunton. The insurance turns out to be valid, so they move on to the bottle o' beer problem and break out the breathalyser. He is fortunate in that he blows below the limit – though he still gets a solid lecture; his explanation is that, having just laid loft insulation, he needed something to clear his throat of all the dusty yuck, and didn't have enough money for a bottle of juice. Then Mike piles in with the killer blow. It turns out that the driver's driving license is expired. As the Passenger does have a license, they have to breathalyse him too, to make sure that he's fit to drive...

Taff and Mike are on the sneak in the Black ST around Collumpton looking for speeders. They get behind a suitable candidate on the M5 who's been in lane three despite the other two being clear – and going at 90-odd. His numberplate is also somewhat unique – given Taff the chance to hazard a pretty safe bet as to what his name might be. It's a swish car – but the number plate has been modified with illegal spacing. The Driver admits at once to the speed issue, and confirms that Taff is right about his name. The speed is the first issue to be lectured upon, before picking up with the issue of the numberplate. Taff explains the point of legal spacing – with a nice little demonstration courtesy of Raw Cut – and points out that the plates would fail an MOT. It's clear that the modification has been done for vanity reasons rather than to stump ANPR cameras, but that doesn't make it any less illegal. So Taff comes up with an innovative solution for the matter of matching the numberplate to the driver's name – changing his name by Deed poll to the corrected registration number!
