Deed has two difficult new cases in his court. In one, a woman with a brain tumour claims it was caused by using her mobile phone. In another, the defendant in a hit-and-run case seems unfit to stand trial.Meanwhile, in a continuing story-line from the second series, Deed's lover Jo Mills faces a disciplinary tribunal prompted by Sir Ian Rochester and presided over by Sir Monty Everard. Both of them bear grudges against Deed, and he rides to Jo's defence.

Deed has an environmental case before him, in which a company operating a large-scale waste incinerator is accused of damaging people's health by air pollution. Jo Mills represents the parents of a damaged child, but is losing. Then it comes out that the company deliberately hid a fault at the incinerator which made its emissions far worse. Meanwhile, Rufus Barron comes up with evidence to support the claim that Neil Haughton took a bribe on a defence contract. Then the evidence is lost, and Haughton demands that Deed should be impeached for unprofessional conduct.

The case of Diana Hulsey, a single mother with terminal brain cancer who is suing a telephone company, is concluded in Deed's court. The Establishment dreads a verdict in Diana's favour, and Ian Rochester is yet again out to discredit the judge before he can deliver judgement. Rochester conspires with the phone company to accuse Deed of possessing child pornography, and Deed has to work out what to do when he finds it on his laptop.Meanwhile, Jo faces a conundrum when Diana asks her to look after her seven-year-old son when she is dead, which could be at any moment.

He makes an accusation of corruption, despite Jo's misgivings.Meanwhile, Jan Dobbs is in Deed's own court charged with murder, and the hit-and-run case from the previous episode is still not concluded. Of course, the bigwigs of the legal profession are still busy scheming to marginalize both Deed and Jo Mills.

Deed has three drug-dealers in his court accused of a vicious gang killing, and he comes under pressure from government law officers to hear the case without a jury. A witness is killed, and the jury starts to melt away. If the case is abandoned, the dead witness's evidence will be lost, but Deed wrestles with his conscience over setting what to him would be a terrible precedent. Meanwhile, Jo's application to adopt Michael is turned down by the Adoption Panel, who feel she is too busy with her legal career to look after a child. Deed encourages Jo to challenge the Panel's decision in the High Court.

An angry contestant in a TV show kills another competitor on camera, and the show's producers face charges of manslaughter in Deed's court.

Sir Tim becomes violent when Deed keeps questioning the 'accident' which killed Barron.

Jo Mills was planning to take time off work, but then she agrees to defend a man who escaped trial sixteen years before after he was charged with attempted murder. Jo is partly attracted to the case because she recognizes two of the detectives who are mixed up in it.

A charismatic MI5 informer appears in Deed's court charged with battering his wife, and the judge comes under pressure from on high to let him off, as he is an important source of information about 'The Real IRA'. In a second case, three men are accused of using Rohypnol to carry out a date rape, and a pushy young defence counsel rubs the judge up the wrong way.Outside court, Deed flirts with Francesca, a publisher who is married to his antagonist Ian Rochester: their resulting short affair is caught on camera, and a jealous husband is quickly looking for revenge.

After a call girl is found dead in a skip, an Arab sheikh's chauffeur is charged with killing her, but the evidence points to the sheikh himself being involved in the murder. Unfortunately for Deed, the Arab ruler was in London to place a huge order with a British aircraft manufacturer, and pressure is piled on Deed by the British government, as well as by the sheikh's own. The plot thickens when counsel for the prosecution is also killed and Deed's lover, Jo Mills, takes over the case, and when he hears that Georgina Channing, his former wife, is engaged to marry Neil Haughton, the government minister fighting for the aeroplane order. Before long, witnesses disappear and the jury is being interfered with - by the British Government, no less. And then Deed gets an offer they think he can't refuse, when appointment as an Appeal Court judge is dangled before him.

Jason Powell (who is represented by Jo Mills) has heart disease, and the doctors say his only hope of life is in a heart transplant - but he refuses to agree to the operation. His parents want the court to rule against an interim injunction supporting Jason, who clearly understands the risks he faces and who has a good legal case to decide for himself. His parents, Mel and Andy, plead for the heart transplant, and Deed lifts the injunction... but then Jason dies on the operating table, after spending his last moments pleading with the surgeons not to go against his wishes... Meanwhile, Deed's own life is running no more smoothly. Both he and Jo are accused of serious misconduct when she spends the night in his chambers...

Jo Mills leads for the prosecution and Brian Cantwell for the defence when a British member of parliament, Alan Roxborough, is tried on a charge of attempting to murder his boyfriend with a frying pan.

Jo Mills asks him to review the withdrawal of Legal Aid funding in the case of the soldier, who committed suicide after being made ill by vaccines given to him by the British Army.

Deed presides over the murder trial of Maurice Hart, a black defendant who shot and killed the driver of a van which ran over and killed Hart's daughter in a hit and run accident. At the same time, the judge is keen to investigate Hart's attractive defence counsel more closely, and he also jousts over the case with the Commissioner of the Metropolitan Police at a London fencing club. Of course, Deed undertakes these misdemeanours against his professional code in supposedly good causes. These include helping his student daughter Charlie to protest against genetically modified crops (and springing her from the cells when she is arrested) and working out how to free his vigilante defendant.

Deed presides over the case of a young man's death on a building site, in which the well-connected construction company boss is trying to lay the blame on his employees.

Deed presides over a murder trial. An old man suffering from cancer died from a morphine overdose, and his attractive young woman doctor has been charged with murder, on the accusation of the dead man's niece. The doctor is acquitted, following a patholigist's evidence that the cause of death was beta blockers in the medication building up in the old man's liver, so the increase in dose from 50mg to 200mg had not affected the outcome... But then the doctor comes to Deed and confesses that she intended to kill her patient. When the Lord Chancellor's Department gets wind of this development, they suggest Deed was sleeping with the doctor - but with Jo's help, he is able to neutralize this threst.

Continuing the story of a war crimes trial in The Hague. Deed finds the defendant is a victim of the British government's attempts to develop an exit strategy out of the continuing occupation of Iraq by western forces, and he has to balance the interests of justice against the possibility of saving British lives.

Deed questions an unpleasant prison officer closely about the death of Paul Settle, a young prisoner who was stabbed to death and then partly eaten by his cell-mate Ben Bradwell just a week before he was due to get out. The Judge is worried that Settle was black, while Bradwell was known to be a vicious racist. In another case, Deed comes up with a thoughtful sentence for a drunk driver who killed a child. Meanwhile, Deed and Jo seem to be growing apart.

In a case in Deed's court, his daughter Charlie is the junior counsel defending Henry Free - an animal rights activist charged with murder after a fire-bomb at an animal research unit killed an eminent scientist. Then Henry falls out with his leading counsel and asks Charlie to defend him - but Deed advises her not to. Part of Free's defence is that his group had been infiltrated by an officer of MI5, the British secret service, acting as an agent provocateur, and Deed is angry when Charlie reveals the officer's identity in court. Meanwhile, Jo is helping and encouraging Charlie - and she is back with her old flame, Marc Thompson. Deed is losing her.
