Seasons & episodes

Ackland leads a raid on a taxi rank, convinced that a former prostitute arrested for drug dealing is protecting a higher player in the food chain, Danny Gibson. However, the raid only years a small amount of cannabis, until Quinnan and Garfield corner a young boy trying to escape, who is found with several wraps of crack cocaine. But when Gibson eventually surfaces, the tangled web of lies becomes even more complicated.

Boyden and Beech lock horns when an off-duty police officer is arrested for drink-driving by Jarvis, who was unaware of his identity at the time. Beech tries to convince Boyden to fix the blood sample to prevent the officer from being disciplined, but when Monroe recognizes the suspect in custody, Boyden has no choice but to play the situation by the book, leaving Beech in the middle of a very difficult situation.

Beech investigates a series of handbag thefts from cars, but is angered when Skase fails to pursue the chief suspect, instead choosing to hold his small-time accomplice. Meanwhile, Hollis is determined to find out who is responsible for the outbreak of graffiti that has appeared about him on the toilet walls overnight, and despite his initial thoughts that one of his colleagues may be responsible, soon discovers an elaborate overtime scam involving a dodgy cleaner.

Carver goes undercover as a barman to expose an extortion racket, where the owner of a pub is being blackmailed into handing over cash in order to prevent any trouble. However, the operation nearly goes awry when an unknowing Beech arrives at the pub to meet with one of his informants. When Carver's cover is blown, Beech becomes prime suspect for giving the nod to the gang – until CID discover the landlord's wife has been in bed with the gang leader.

Greig and Skase investigate a possible arson attack after a fire burns down a block of flats, killing a young family. Initially, the two seats of fire appear to suggest a deliberate attack, but when the father of the young children reveals they had been without power and were lighting fires to stay warm, Greig and Skase's attention is turned to the dodgy landlord, who they are determined to nail for involuntary manslaughter and neglect of duty.

Conway enlists Carver and his chums from the local Scuba Diving club to help clean up a dock which has been a regular fly-tipping spot. However, during their expedition, one of Carver's friends finds a corpse. Meanwhile, Deakin and Lines are on the trail of one of Deakin's snouts, who has gone missing. When they hear of Carver's find, they have a suspect in mind, before the body is even retrieved. But could the death be an entirely innocent matter?

Beech and Carver investigate the hit-and-run of a young football star, and initially suspect a rival agent may be responsible for the attack. However, with many differing stories from those involved, they soon discover that the real culprit may in fact be the man's own girlfriend. Meanwhile, Skase is left in the lurch by Beech to deal with an old robbery case, but soon discovers the two cases they have been working on may be linked.

Quinnan and Page investigate when a man is assaulted by his 12-year-old daughter, having been convinced into speaking out by her shady uncle. However, a tangled web of lies begins to unravel when stories about both men prove to be untrue, and that the vengeance between them is the result of an old post office robbery which the pair pulled off, and a subsequent car accident which left one of the men paralyzed.

Cryer is taken hostage at gunpoint by an aggrieved husband who has decided to take drastic action over a custody case. After accidentally firing the gun at his ex-wife, Cryer is then forced to make a difficult decision – save the victim and allow the man to commit suicide or risk the woman's life to prevent him from doing so. Meanwhile, with the canteen staff off for the night, Hollis takes his task of cooking meals for the prisoners a little too far.

Quinnan and Hollis investigate when a store detective renowned for his bravery is accused of assaulting a shoplifter. Although the man initially admits to the crime, following a quiet word with Beech, he soon changes his story. However, despite their anger at the sergeant for his unwanted interference, they soon discover the case is not an isolated incident, and soon discover a series of assaults on frightened shoplifters.

Pearce learns that his transfer out of Sun Hill has been approved, but takes on one last case where he investigates a man being blackmailed by an escort agency. Meanwhile, Datta is accompanying a former tom to court for a custody hearing. However, when Pearce learns the two cases are connected, he uses leverage to collect evidence against the agency manager, unwittingly taking down Greig's snout in the process.

Stritch and Monroe clash over a series of new timekeeping 'exercises' being implemented to improve response times. Meanwhile, Loxton and Slater manage to catch up with a group of racist attackers whom CID are desperate to nail. As they give chase into a derelict building, Loxton becomes involved in a fight with one of the suspects, who steps through an open door and falls to his death. Stritch soon finds the relief laying the blame firmly at his door.

Deakin and Woods are in court for the trial of a dangerous drug dealer, Benji White, with assistance from former Sun Hill alumni Jo Morgan – now working for the regional crime squad.

Meanwhile, McCann builds a bond with a young boy who is arrested after his social worker asks him to press charges over some broken crockery.

Deakin and Morgan are back in court following the two-day adjournment, but find themselves in an even worse position when one of the star witnesses takes an overdose and subsequently dies, and the other turns up to court high on drugs. As the defendant escapes a jail sentence and is only charged with a minor offence, Lines and Croft arrive at court to re-arrest the suspect with a file full of fresh evidence against him.

Ackland tries to find a young baby who has been snatched from her mother's car, but is surprised to discover the prime suspect is pregnant herself – until a search of her house reveals some very clever costumes to improvise stages of a pregnancy. As the search for the child yields no clues, Ackland makes a brave decision to continue the interview off the record in order to secure the baby's safety.

When a bomb destroys a local electrical shop CID embark on a frantic search for a second device.

Carver and Woods suspect a petty thief of a much more serious offence. But are they off the mark?

WPC Ackland and PC Loxton are on foot patrol when they are approached by a Mrs Henry with a minor complaint. A shot rings out, hitting Mrs Henry and SO19 are quickly on the scene to evacuate the officers and the wounded woman. CID, including WDS Jo Morgan who has been seconded to Sun Hill as a liaison to the Regional Crime Squad, can find no reason why the woman would be the target of a sniper. PC Loxton, who is testifying in a court case later in the day is assumed to be the target and is given SO1 protection, although subsequent raids of the suspect's property put him in the clear. That night however, as Loxton slumbers in a safe house, someone firebombs June Ackland's flat.

As it becomes clear that someone wants June Ackland dead, she is horrified to find CID digging through her painful past to discover the killer's identity. Tired of being holed up in a safe house, Ackland decides to go back on duty, as this may also draw the killer out of hiding. There is a close shave when she is seperated from Sgt Cryer on street patrol and a man pulls an imitation gun on her, although she is rescued by a covert SO1 officer. Meanwhile, a witness to the arson on Ackland's flat, Mrs Cooper, comes into the station to make a statement.

The identity of the man trying to kill June Ackland may be revealed when an ex-Army officer is overheard boasting that he was paid to ""kill a copper"". CID link him to a young man who committed suicide in prison after Ackland arrested him for dealing drugs on the Jasmine Allen. WDS Jo Morgan realises that their witness, Mrs Cooper, is behind the plan as she turns out to be the mother of the dead boy. Mrs Cooper is arrested for conspiracy to murder, and she reveals that the assassin is lying in wait for Ackland at the safe house. As Ackland and an SO1 team head off to the safe house to draw the killer out, they are ambushed by a man on a motorbike just outside the station, and Jo Morgan is killed in a hail of gunfire as she rushes to warn them.

Sun Hill is in shock after the death of WDS Jo Morgan, none more so than WPC Ackland who is still racked with guilt over her death, and PC Loxton who is forced to apologise to a pair of loudmouthed youths after he threatens them.

Beech organises an obbo on a known fence in an attempt to catch him in the process of selling stolen gear, but trying to escape, the thief jumps from a second storey balcony. As he begins to recover in hospital, his accomplice refuses to give him up, but it's not until Quinnan manages to make a breakthrough with the man's distraught wife that they finally discover who was responsible for the raid during which the gear was stolen.

Keane and Jarvis attempt to keep the peace at a dodgy backstreet auction on the Jasmine Allen where the customers are furious of being duped out of hundreds of pounds. However, the auctioneer is ambushed on his way out of the estate, and the pair try to find out who was responsible for catapulting a scaffolding pole through the windscreen of his van, causing a major crash. Keane turns a blind eye when she finds some of the goods stolen during the ambush.

Quinnan and Datta follow up reports of a disturbance in a quiet suburban street, and uncover a family who have barricaded themselves in their home.
