The Bill

P.C. Litten recognises a photo of a wanted armed robber, but takes the information to D.I. Galloway instead of Sgt. Cryer, and gets into trouble with both men. Meanwhile, a gang of thugs is robbing local shopkeepers, and P.C. Edwards purses a mugger into a derelict building and is trapped when the floor collapses beneath him.

The discovery of a body of a teenage suicide leaves a bitter taste in Ackland's mouth, and finding herself being drawn into a seedy world of pornography, drugs and prostitution, Ackland considers leaving Sun Hill for good after the situation is made by worse by Galloway, who gives her a hard time over calling him out of bed on a Sunday morning. When it is discovered that the girl was three months pregnant at the time of her death, Galloway goes all out to make sure the investigation doesn't drag the girl's name through the mud, and her parents are protected from finding out what their daughter was really like.

After a residents' meeting complaining about the drug problem on their estate, DI Galloway mentions that he had heard that an old illegal club has reopened in an abandoned theatre complex - this time dealing drugs. He asks a parent, Tombo Robinson, who used to be involved in the club, if he will infiltrate it to confirm Galloway's suspicions. Tombo reluctantly agrees, and meets with Galloway to tell him that a huge drug deal is going down that afternoon. Galloway quickly arranges a warrant, and sets about organising a huge raid on the club. The raid runs according to plan, but Tombo is stabbed by a dealer as he tries to let the police into the building. PC Edwards and Carver give chase to the dealer, but are alarmed when the suspect speeds off in a car bearing diplomatic plates. Galloway checks up on Tombo in hospital, and is shocked to discover that he has died and was a heroin addict. Returning to the station, Galloway is furious when Ch. Supt. Brownlow, a Home Office representative,

PC Dave Litten is on secondment to CID, and is desperate to impress his boss, DI Roy Galloway. Galloway and Litten are about to have a meal at the local pub when a call comes through that a valuable necklace has been stolen from a local aristocrat, Lord Barstow-Smythe. Traffic problems hold them back as they race across Sun Hill trying to get there before the ""woodentops"". With Galloway and DS Roach busy, Litten talks to a local reporter and ends up mentioned in the local paper. Shortly afterwards, he is contacted by a mysterious stranger who offers to locate the burglers if Litten can convince Barstow-Smythe's insurance company to pay him the reward up-front. The Stranger then sets up two young lads to take the fall for the theft, and Litten proudly arrests them. Galloway recognises the MO of the case as that of a notorious conman, and lambasts Litten for his stupidity.

After a briefcase is found by a young car thief, Det. Insp. Galloway thinks he can finally nick the 'Arthur Daley' of Sun Hill. Because of car problems he is unable to interview his chief suspect. After a warehouse fire that is supposed to convince Galloway the porn magazines were destroyed, they arrive back at the station just as the van carrying them drives away - having been parked at the back entrance for 24 hours.

Alfie Mullins is a non-returned prisoner, not a dangerous prisoner as reported. He is an old-fashioned safe-cracker who, just as he is returning to the prison, is approached by one of a gang of thieves who want Alfie to open a safe they pinched. While they are talking Alfie is accidentally killed. The safe is rigged to explode by remote control which P.C. Carver accidentally sets off when he uses his radio.

A tip in a counterfeit perfume case pulls in two very old aged pensioners who appear to have been pinching things since WWII. But after leading Carver and Ackland in a merry chase it turns out they aren't the real culprits.
