Their first case is that of a woman, eventually identified as Sylvia Carter, whose remains are found on the railway tracks after being run over by several trains. She worked for a local sandwich maker and Frost is convinced she was having an affair with someone. Dr. Helena Gibson, a senior surgeon at the local hospital in Denton, goes missing over a weekend. From all accounts she was in on Saturday but didn't show up at a colleague's house for lunch on Sunday.

In fact, there is an investigation into an abnormally large number of post-operative deaths at Denton General but as Frost learns, everyone who dies seems to have done so while occupying bed 5.

Two young men are tricked by their girlfriends into stripping themselves nude for a midnight swim, during which the girls run off with the boys' clothes, leaving them to streak through Denton. One is arrested but the other, Roman Cassell, gets back to his office where, the next day, he is found beaten to death. Suspicion falls on Jason Cohu and his father-in-law Joshua Ray, who blame Cassell for the death of Jason's wife and were in the vicinity of the office that night. Joshua admits to the murder but Frost believes he is innocent, misguidedly protecting his son-in-law and CCTV footage proves him right. At the same time Carl Meyer is released from a twenty year prison term. When he was a young boy he was accused of murdering a little girl with whom he used to play and with whose corpse he was found. Her cousin disappeared on the same day and he was also accused of killing her. The girls' family conduct a vendetta against him to which he shows no malice...
2	"Dead End"	David Gilman	Roger Bamford	8.52	19 October 2008 (2008-10-19)
The Heal family is appalled to see the man whose lorry killed three of their members some years earlier is driving a bus. Because the lorry's mechanism was faulty he was acquitted of dangerous driving but the Heals are not happy and Andy Heal goes to the bus depot for a confrontation. Later the driver and his conductress are abducted from their bus. The conductress is diabetic and needs her insulin shots and, after a television appeal, she is dumped, alive, in town, not far from an alley where a clown is found dead. He recently entertained at a children's party where one of the mothers has a pathological phobia of clowns, and believes she attacked him without knowing. However, it turns out that he was also a thief, robbing the houses he visited and his killer may have been somebody else. In solving the death and finding the bus driver Frost's work is not helped by having to work with DS Annie Marsh (Cherie Lunghi), who once reported him for being unprofessional.
3	"In the Public Interest"	Thomas Ellice	Paul Harrison	8.16	26 October 2008 (2008-10-26)
The naked bodies of three young men are found, arranged in a triangle, in a grave at an old burial site and an American anthropologist insists to Frost that these are ritual killings. However the fact that she has a book to promote and reports of unrest among local Eastern European immigrant workers suggest that the murders are not mystical at all. Ever the maverick, Frost enjoys crossing swords with James Callum, an unpleasant local business man who is going to tear down the local youth club to make way for new offices. When Callum's fitness instructress mistress, Rosemary, is found dead on her houseboat, and evidence also suggests that another of Callum's girlfriends died in suspicious circumstances some years earlier Frost cannot wait to pounce. First, however, he must get past Callum's adoring personal assistant, Michael. Perhaps a spot of breaking and entering would help Frost find the clues he is after.

1	"If Dogs Run Free (Part One)"	Michael Russell	Paul Harrison	8.79	4 April 2010 (2010-04-04)
Frost and his men assist RSPCA officer Christine Moorhead in smashing an illegal dog-fighting ring but its organiser, local gangster Gerry Berland, eludes them. One of Christine's helpers, Brian, is stabbed to death by Berland's thuggish son Sean, who believes he set the police on the ring, and Christine recognises him and his accomplice, Neil. Berland arranges alibis for the boys and, though initially appalled, his wife Sally colludes with him as he has always run her life. She persuades Neil's honest and horrified parents to go along with the lie. Having failed to warn Christine off, Berland sends a thug, Lisowski, to torch the RSPCA unit with Christine inside it with her rescued dogs. Meanwhile a mysterious criminal is duplicating unsolved crimes on Frost's books from years earlier and, as he goes to rescue Christine, Jack finds chalked on his car's windscreen, 'You Die Next.'
2	"If Dogs Run Free (Part Two)"	Michael Russell	Paul Harrison	9.94	5 April 2010 (2010-04-05)
Christine survives her ordeal and grows closer to Jack, who meets her apparently friendly ex-husband. To silence Lisowski, a drug addict, Berland gives him an extra strong fix, which kills him. Frost realises the two men knew each other but decides to bide his time. However he has a piece of good fortune when Salmond, Berland's cocky solicitor, has his car stolen by joy-riding colleagues and Salmond's large personal stash of cocaine is found in the car. Frost levers him into revealing the location of the site where Berland trains his fighting dogs, and from here on Berland's world collapses. Sean kills himself and Sally leaves him, watched by Neil's mother, who takes her boy to the police to confess everything. Berland, finally recognising the pain of losing a loved one, allows Frost to arrest him in peace. In an epilogue to the episode and, indeed, the whole series, Christine and Jack are seen rehearsing their wedding. Later, at her house, Christine's ex-husband says that he doesn't want her to marry Frost, but instead wants to get back together with her. When Christine rejects him he is on the verge of becoming violent, but leaves quietly. On the day of the wedding he is seen parked down the street, watching the scene, while drinking from a flask. Frost arrives at the church by car, driven by George Toolan, but before the two get out of the vehicle, superintendent Mullett hands them their boutonnières. Christine's ex undoes his seat-belt and speeds towards the men, ramming the car on the driver's side door. All three men are taken to hospital, but while Mullett and Frost are only bruised, George Toolan dies in the end from his injuries. A final scene shows Jack saying goodbye to George's coffin, and telling Christine that he is ready to live a life outside of his vocation of being a policeman. Alternative endings were written and filmed for the series finale. In one ending, Mullett dies instead of George Toolan. In another alternative, Frost dies instead of George Toolan.
