Exeter in the dead of the night. Darryl and Murphy are on their way to deal with a couple of youths who are in the process of scaring the hell out of people at a petrol station. By the time the cops arrive, the antagonists have gone, but the damage they've left is pretty clear. A local unit has stopped two likely suspects who are loud, obnoxious and bladdered. One of them finds it highly amusing that Darryl is being filmed, though this dissolves once he discovers that his friend is being arrested under section 5 of the Public Order Act. From the ensuing argument, it's not long before the officers have a matched set, though putting the pair into the back of the van is almost as challenging as having to critique their dancing.

The TAG are getting ready for yet another raid, this one in Paignton. They need to act fast, to ensure that any drugs in the property are still there once they're in. Fortunately they don't repeat their epic entry from Episode nine and are swiftly inside. The occupants settled down and cuffed, the search begins. It doesn't take long to find a hydroponics unit, a small stash of heroin and a tasty little wodge of cash. There's no evidence that there's enough to deal, but there won't be any for personal use either now.

Back in Exeter, now with Lee. Paramedics have asked for Police assistance at a railway station after they approached a man who pulled a knife on them. Mindful of both his safety and his dog's, Lee keeps Sharp on a tight lead and effectively straddles him to keep him from getting too far ahead. A tentative peek onto the platform leads them round into a shelter where a man is lurking. He stil has the reported knife, which he quickly relinquishes, and states that he only wants to get home. Sharp settles down to one side while Lee searches the man, who is not in the best of emotional health following a pretty rotten day, and cuffs him before sympathetically leading him away to a waiting van.

It's a busy night for Lee. He's off to find another man with a knife. The man has, apparently, just rung the police to say he has a knife with him in order to defend his mother against someone who – he claims – has threatened her. It's all a bit confusing, but Lee's nearby and heads in to investigate. The man readily admits to having a knife, which he immediately drops when Lee asks him to. It seems that he's been standing guard outside the house – though he was less willing to comply when asked who he was protecting her from. All Lee can do in this case, therefore, is arrest him.

Gareth is in Tiverton now, and is investigating some messy damage caused by three drunks who – when challenged – responded with profane abuse. While Gareth can't fix the mess, he can find the perpetrators, as they've left a trail of damage in their wake which requires him to lug rubbish bins out of the road. As there's only one place left at that time of night which still serves booze, Gareth checks out the 24-hour Tesco where the three likely lads are sat outside, claiming to have been there all along. They are also something on the obnoxious side, but staff and CCTV show that they've come from exactly the direction they claim not to have, and one of them wasn't exactly peaceable in his behaviour as they approached. With no hard evidence, he can't arrest them for the damage, but a quick check on whether there's a drink ban in the car park gives them enough reason to depart without further ado.

Roger and Giles are patrolling in Plymouth City Centre, though it's something of a stop-start affair as the traffic's pretty awful. Giles's attention has been caught by a car which has come all the way round a roundabout to go back the way it's come. As it appears to have been going round and round in circles, he decides to give it a tug to find out what's going on. It seems that the owner of the car had parked it on double yellows and, rather than see his friend get fined, one of the passengers quickly took it for a trundle to avoid a ticket. Unfortunately, not being insured to do so, he's now been driving it illegally. The driver, upon return, is not impressed, as he knows that his friend wasn't insured to drive his car. So, in attempting to save his friend from a £60 parking fine, he ended up giving himself a day in court and a £525 fine for having no insurance – and six points on his license. Ouch.

Still in Plymouth, Roger and Giles are suddenly flagged down by a pedestrian who alerts them to a man who has collapsed alongside some bins. The man's report is that the fellow was the subject of some nasty verbal abuse, and now appears to be having a heart attack. A quick spot of investigating reveals someone familiar to Giles, for boozy reasons as it's someone he's dealt with before – and for much the same reason. Far from being abused, he's been the one doing the abusing, and Giles has a quick word with the man who was being yelled at. As the man doesn't want to take it any further, so the pair help the fellow back to his feet and send him on his way. Which is – it seems – straight back to a pub...

Darryl is in Exeter with Murphy, and is heading across town to assist a local unit who needs some assistance getting a wanted man to come out of his house. The man concerned has broken the terms of his suspended sentence, so it's off to the nick for him. Needless to say, this does not appeal, so the man has – apparently – taken refuge in the loft. With no alternative, the door is bashed in, which gets Murphy terribly excited. Once inside, they find that the television is on, as are the lights, so the 'going into hiding' thing must have taken place at the last minute. The man can't have left; not with a cadre of coppers parked outside for the last hour or so. With nowhere else to look, someone goes up into the loft with a torch, and eventually the fugitive emerges from amongst a pile of insulation.
