Episode list

A security guard is murdered during a payroll snatch. The local police force under Chief Superintendent Canning have no luck in catching the robbers and Canning is reluctant to work with Regan when the Sweeney are called in, frequently clashing with him. When Regan apprehends all the gang without telling him, Canning is far from happy. Regan is accused of corruption nine years earlier and Canning, his contemporary, refuses to help him. Fortunately Carter finds someone who will, but the whole experience leaves Regan extremely bitter.

Regan is staking out vicious robber Vic Tolman and his girl-friend Lyn Hurst, who have stolen the wages from the firm where Lyn worked. A surveillance is in progress on the flat belonging to Lyn's sister Joan, who is looking after her daughter. Regan and Carter eventually break into the flat and use the two women as bait for Tolman. He turns up but things do not go as planned.

A hung-over Regan pulls local Lothario Lukey Sparrow for his part in the theft of thirty thousand pounds worth of mercury. The boy has an alibi - he was in bed with a married woman, but wants it kept quiet, as he is getting wed next day, to Linda, daughter of the fearsome Lily Rix. Regan proves Lukey's part in the crime but needs to reach him before some very dangerous heavies do. Either way the wedding seems unlikely to go ahead, subjecting Regan to the full wrath of Mrs. Rix.

After Regan gets a tip about an upcoming robbery from a trusted informant, the gang kidnaps his daughter to blackmail him into inaction.

Vic Labbett, a violent robber who fled England following a robbery, has now returned from exile but only temporarily. His aim is to pick up the cash from the heist and convert it into diamonds and fly out of the country again. Regan is on to him and although Labbett initially eludes him, a muddy car chase across the air-field leads to his downfall.

Robert Hargreaves, who has an apparently distinguished military background, joins Regan's team. However, at a raid on a caravan site to capture a gang of ex-soldiers who have carried out a violent robbery and are armed, Hargreaves bottles it and cowers behind a tree. Running against the general tide of opinion, Regan believes he is unsuitable for the job but needs to find out more.

Two young villains, Tyson and Jenner, working for gang boss Tony Kirby, are relieved of the spoils of their robbery by a mysterious gun-man, who shoots Jenner in the leg. Nobody knows who he is until Regan has a word with Jenner's disgruntled father-in-law, which leads to a shoot-out in a theatre. At the same time Regan is made a tempting offer to go into private security work.

Giles Nunn and Carrie Selhurst are an upper crust couple who, partly for kicks and for the profits, commit highway robbery in lonely country lanes, along with the lower class boy Tommy Garret, whose dad is a friend of George Carter. Regan is on to them and Carrie gets arrested, but her unwillingness to cooperate leads to the death of the next victim.

Carter's schoolteacher wife Alison is deliberately killed by a hit-and-run driver while posting his football pools. She had actually borrowed a coat from Judy, the French mistress, who consequently goes on the run as it was clear that she was the intended victim. On her trips to France with her class, she had become involved with a gang for whom she would smuggle goods but finally made it clear that she wanted out, hence the attempt to silence her. Regan must find her before Crofts, the gang boss, does.

Colin MacGruder and Ray Stackpole, two Australians with the theme "Nice 'n' easy does it", commit eleven armed robberies, in each case stealing Kruger Rands purchased from the same firm, the managing director's secretary tipping them off as to the whereabouts of the coins. They also pay an informant to make it look as if Haskins is taking a bribe and plant money in his greenhouse, so that he is suspended. Regan traces the Kruger Rand connection but all the villains escape. However, the absence of witnesses means that Haskins is completely exonerated and reinstated.
