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.
