Sgts. Peters and Penny apprehend a man standing outside the station waiting to attack P.C. Muswell (who had left the force six months previously). P.C. Jim Carver begins his CID training by working on an all night obbo with D.S. Ted Roach. Due to Carver's inexperience and Roach's lax attitude, they both miss a flatbed trailer stealing a digger from a building site. Roach and Carver follow up their suspiscions about the site security guard, and find he has stolen the equipment. Back at Sun Hill, D.I. Roy Galloway is being investigated by the Home Office for allegedly forcing a confession from a murder suspect under duress at his last posting. Galloway is cleared of wrongdoing due to lack of evidence, but Ch. Supt. Brownlow warns him that his old-school policing methods may be his undoing. In a suprising turn of events, one of P.C. Reg Hollis's rare walks on the beat with W.P.C. June Ackland leads to him apprehending an armed gunman single-handedly from the Sun Hill D.H.S.S. office.

Ch. Supt. Brownlow and D.I. Galloway lead a massive raid on a drug den on a local council estate which escalates into a full-blown riot, but half a million pounds worth of crack cocaine is recovered. P.C. Melvin loses a handcuffed prisoner in the confusion, but he is arrested by P.C. Hollis when he turns up at the station asking for his handcuffs to be removed. The operation is down to D.C. Dashwood, whose snout is feeding them information on the main drug dealer. Meeting with the snout to get the location of the main drug lab, Dashwood is alarmed when P.C. Carver recognises his informant as Dougie Gardiner. C.I.D. raid the location given to Dashwood by Gardiner, but find nothing except a student squat. Desperate to arrest the dealer, and furious with Dashwood for lying about his snout, Galloway stakes out the dealer's Range Rover in a car park, despite Brownlow insisting he end the operation. When a borough councillor complains to Insp. Kite about the estate raid, it is discovered tha

The Deputy Assistant Commissioner visits the station at the same time as a brownie pack. The "Tom Squad" is conducting a crackdown on prostitution in Sun Hill, and D.S. Roach reluctantly meets with some social workers about a girl being abused by her mother.

There's been a shooting, but none of the neighbours seem to have witnessed anything. While chasing a possible suspect, Sgt. Bob Cryer hits a pedestrian. During door to door inquiries P.C. Yorkie Smith discovers a man with exotic animals including snakes, owls and a crocodile in his bathtub. D.S. Roach is attacked by some thugs, and the next day tries to beat them with an iron bar until P.C. Carver stops him. His attackers are later kneecapped as a message to D.I. Galloway as to who really is the law on the manor.

Residents take action against a women's refuge in their area, while P.C. Yorkie Smith gives advice to the husband of a woman at the refuge. As D.I. Galloway gets tough with his detectives about the clear up rates of burglaries in the area, W.P.C. Martella and P.C. Edwards pull in a man suspected of three burglaries. P.C. Edwards is getting a hard time because of his impending marriage.

A boy causes a bus accident by throwing a milk bottle at it. He has 6 siblings. P.C.Frank marks bikes for children. A bike with the wrong postcode is stolen. Shaw has a car accident and some booze in the car gets broken and then Ackland drops another box. An old lady, conned out of five pounds, turns out to be one of a number of elderly people targeted by a group of children.

D.S. Roach theorises a mysterious drowning is the work of the British secret service. D.I. Galloway hits a black cab and arrests the driver, causing half the cabbies in London to blockade the station.

D.I. Galloway wants eight men for an identity parade after an attack on a woman. They run into a mob of football supporters who are ""persuaded"" to help them out. P.C. Melvin helps a lady who has locked herself out of her car. CIB (Complaints Investigation Bureau) arrives at the station and none of the early shift are allowed to leave. Turns out to be an allegation of a copper pocketing a parking fine. Nerves are frayed on the relief, particularly those of P.C. Nick Shaw and W.P.C. June Ackland who come under particular scrutiny as they were on patrol at the time. Shaw is in strife for not declaring Ackland as a passenger in his panda car. As Ackland and Shaw are interviewed, another report of the bent coppers comes in, and CID arrest a mechanic from the police garage and his girlfriend who were posing as police officers and pocketing on-the-spot fines. P.C. Stamp spills a cup of coffee on the P.C. Patel's computer keyboard causing Patel to lose all the work he has done.

Martella applies for a position in the Bermuda police force, but after being punched during a fight, and failing to prevent a suicide jumper, she feels she is not up to the job and withdraws her application. Roach investigates a fight at a hostel for drunks. Patel investigates another racial attack. During followup, Carver is worried about himself not liking Asians. Penny has started yoga and thinks everyone else should do it too.

W.P.C. June Ackland's father is dying in hospital. P.C. Taffy Edwards is given traffic duty after arriving late for parade. P.C. Jim Carver gets beaten up in a bus queue. Sgt. Cryer and P.C. Patel investigate an alleged rape. Insp. Kite is set up and sent to collect mud samples because of a suspected radioactive leak.

Half the relief, including CID, are at a hotel guarding a sequestered jury in a gangland murder trial.

Sgt. Penny is asked by a landlord to talk to a lady on the top floor who is keeping cats. He is shot through the door after finding out his radio doesn't work. When Penny doesn't respond to radio calls, the station is worried about him and organises a search party. The landlord turns up at the station and talks to D.I. Galloway who doesn't make the connection. Insp. Kite nicks four people for breach of peace that he caused. A suspected poisoning of chocolate bars is traced to a supermarket.
