In court, Deed has to judge the case of a couple who are fighting their local council over a police communications mast on the roof of the building they live in. 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. Of course, the government doesn't want the case to be heard.

Deed's superiors want him out of the way, and they arrange for him to be called for jury service on a case which will not be over quickly - a murder trial.

In court, a teenage nanny from the Ukraine is accused of killing Baby Jonathan by shaking him, which she denies. As a juryman, Deed wants to see more medical evidence. Then he discovers a cross-over with a case of Jo's, in which she has evidence that the effects of the MMR vaccine could have led to Baby Jonathan's death.

Meanwhile, Marc Thompson is asked to travel to South Africa, to give evidence about its child vaccination program - and Jo begins to have doubts about marrying him. 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.
