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.

Deed encourages Jo to challenge the Panel's decision in the High Court.

Deed has the case before him of a man charged with killing a paedophile, but the jury find the defendant not guilty. After his acquittal, the man calls a press conference and sends out a message calling for similar actions elsewhere. Meanwhile, Marc Thompson, Michael's real father, arrives in England from overseas. This seems to end Jo's hopes of adopting Michael, but she starts dating the new arrival, sending Deed into a jealous rage. Deed then unwisely starts a new affair with a woman appearing in his court as a claimant in an action, and Jo decides to move with Marc to South Africa.

Jo is threatened, and Deed comes home to help her.

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.
