In a case in Deed's court, his daughter Charlie is the junior counsel defending Henry Free - an animal rights activist charged with murder after a fire-bomb at an animal research unit killed an eminent scientist. 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.
