Gareth's in Exeter, heading out to investigate reports of a group of youths in a lane behind a pub who've had a lot of alcohol, and a bit of a barney. One of them, it seems, has picked up a metal bar, so Finn has to stay put. He encounters a local officer who's stopped a cyclist, who isn't carrying a metal bar, but he is carrying a knife. He admits to this without hesitation, apparently under the impression that there's nothing wrong with going about in public armed with a six inch steak knife. Upon being informed otherwise, he decides to threaten to start spitting, and is immediately plonked on the ground. He then makes things a little worse by claiming to be HIV positive, which would make his saliva slightly more than just unpleasantly messy. Matters are not improved by the arrival of a friend of the detainee, who may also have a weapon. By this time, however, the cavalry have arrived, which makes life a lot easier, but it takes a little longer to get things fully under control with the armed cyclist, who has been drinking most of the day and now claiming that he didn't actually know he had the knife at all. The drunken friend pushes things too far and gets nicked for his drunkenness and appalling language, joining his pal in the back of a van.

TAG time, and we join C section in Torquay to execute a drugs warrant. They've got another plastic door to get through, but decide to resort to a spot of subterfuge to avoid a repeat of last week's shenanigans. John and Mark set off ahead of the pack in their uniforms, pretending to conduct house to house enquiries, while everyone else, in protective gear, lurks behind. Their efforts prove sadly in vain, as the house appears empty, and the ram is deployed. Instead of busting the door itself, it takes out on the bottom panel, creating a small hole which can be crawled through without difficulty. Once inside, they discover the familiar woody fragrance of weed – and find themselves in the midst of a small scale cannabis farm, as well as a 'How To Grow Mind Altering Substances for Fun and Profit'-type manual and a wodge of cash. Removing samples, everyone then forms a human chain to remove the rest of the stuff for transfer to a skip. Then comes news that the house occupants have been detained elsewhere. As John puts it: 'A good day'.

Jim and Chris are patrolling in Exeter and find themselves behind a man who's driving suggests it's as much alcohol as petrol fuelled. Upon opening the door it is very, very apparent to Chris that the driver is fully pickled – and wobbly to the extent that the breathalyser is unnecessary. Things are made more difficult by the fact that the driver is Polish, and, being magnificently whammed, barely has any powers of speech in any language, never mind English. This being the case, they carefully guide him in the right direction of the nick, and hand him over to Mark's tender care in the intoxilyser room, courtesy of some assistance from an interpreter over the telephone. It takes a bit of time to get him to blow down the tube for long enough, but once he does, he shows as being over three and a half times over the limit as well as not having a driving license. Ouch.

Rejoining Gareth, it's the early hours in Exeter, and he's been called to a shopping precinct to help break up a bit of an altercation between around ten youngsters. They've moved on by the time he arrives, but things are still somewhat confused, with witnesses claiming that a single person has been the focus of the unpleasantness. It takes a bit of time for Gareth to persuade the youth concerned to point out the people who have been mistreating him, but eventually he does, despite the usual noisy interference that seems to go with questioning one person amidst a bunch of other youths. Eventually, Gareth has to walk him off to one side to try to get rid of the noisy interjections from his friends, and finally gets a clearer picture of what happened – primarily the usual type of 'respect' orientated altercation between young people, though with added racial overtones. Statement taken, he and his colleagues then attempt to persuade a large crew of gobby, obnoxious teenagers to move on and go home. Eventually.

Chris is back with Mike again, and they're in Exeter behind a car which has twitched Mike's crim radar. The ANPR backs up Mike's assessment, as the car has no MOT, so they pull it. The car is, apparently, booked in for an MOT 'next week'; but, as Chris points out, that means it shouldn't be on the road in the interim. Things are not improved by the discovery that his license is marked as 'revoked'. As the driver is appealing this, he believed he could drive until the matter was settled one way or the other – so Chris has to advise him that he's wrong about that as well. Before advising him that his car is being seized for being driven with no license or MOT. Whoops.

Giles and Roger are behind a manky looking vehicle just outside Plymouth. They attempt to stop it – only for the driver to completely fail to see them behind him. Sirens are required to capture his attention. It's a truly knackered old car, with no MOT, and a Two year old tax disc. When asked why he's driving the car, he claims it's because he 'has to' as he 'lives in a rural area'. Which means that it's perfectly okay in his book to drive it, despite being illegal to do so. Fortunately, as Giles is present, if it's that dangerous, he can prohibit it; and he finds plenty of reason to do just that from the state of the tyres alone, never mind the leaking brake fluid and wrecked wipers. In addition, the driver's explanation for not paying his tax is that he refuses to do so as the money won't be used on the road. Not only that, he is convinced his car is perfectly safe and demands that Giles has no right to take the car off him. The answer to that? Tough!
