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 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.

In Deed's court, Jo Mills acts for a mother whose former husband, Paul Robson-Alan, wants their baby to be given the 'MMR' vaccination. Robson-Alan is a British Government health adviser, and the outcome of the case is important to the political credibility of the Health Department. But Paul's ex-wife, Marika, believes the MMR jab is dangerous - and some dramatic new evidence is produced on that. Meanwhile, Jo's wedding to Marc is still on, but she is so busy that she forgets to turn up for the rehearsal of the service. Jo is angry with Deed when he forces her to attend a legal meeting on the morning of the wedding itself. Will she get to the altar on time, and will she go through with it?

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.

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.

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.

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...

After quarreling with Marc, she starts to see Deed again. But then she also quarrels with Deed, who still seems to have another woman in his life - one of his fellow judges.

Deed risks a constitutional crisis in pursuit of justice for a soldier?s family. 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 is reluctant, as the case has been heard and closed by another judge. His only course is to accuse the other judge of bias. When he does so, he causes consternation in the British government.

Gilly Bridges has motor-neurone disease, while her husband Jake has stomach cancer, which they claim are connected with the 'tetra' mast. The incidence of both diseases in the Bridges' block of flats is many times the statistical norm. Jo represents Jake and Gilly Bridges, while Deed's former wife George appears for the defendant council. Then Deed receives an application from Rose Hussein, the English wife of a former government minister from Iraq. Rose believes depleted uranium used by the British Army in its tank shells killed her family - and she wants the court to establish the facts.

Deed has to judge a case concerning Jo's boyfriend, Marc Thompson. Marc wants to take the decision not to resuscitate a two-year old patient at his hospital who has a weak heart and is in a coma, if the child's heart stops again, but the parents disagree. In another case, Deed has to sentence a young thief, and the youth then dies in custody. All this brings back Deed's memories of his own traumatic childhood. He is spoiling for a fight and argues with Jo - who announces that she has decided to marry Marc.

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.

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.

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.
