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 gets angry when a brother judge deals leniently with a man convicted of political offences from whom the judge has had certain favours. 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.

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. As usual, there is a conspiracy in the background to pervert the course of justice, which may be connected to Roxborough's opposition to certain British arms deals.Meanwhile, Deed goes into therapy and has a brief affair with his therapist.
