William Garrow continues to defend the victms of rough justice when he wins the case of a prostitute accused of murdering a client.

Garrow and Southouse's association is still strained until a desperate Mary Hamer arrives in Southouse's office, begging for Garrow to defend her husband. Joseph Hamer has been languishing in Newgate Prison without charge for many months after being arrested on suspicion of sedition.

Joseph's case is followed closely by the Secretary of State, Viscount Melville, and Sir Arthur Hill, who engineer charges of high treason against him.

Lady Sarah admits to a devastated Garrow that they have no future together. After learning of her husband's role in the plot against Joseph Hamer, she intervenes and the trial takes a surprising turn.

Having failed to save a twelve year old mute boy from the gallows,Garrow enters the civil court to hear Hill's accusation of adultery against him in a deeply depressed mood,despite Sarah's assurances. Silvester,previously his adversary,defends him in the spirit of fair play and does well,demolishing Hill's Admiralty cronies,the prosecution witnesses,whilst Mary,Sarah's loyal maid,refuses to perjure herself. However,it is the dogged and devoted Soutouse who saves the day by bringing in a surprise,last minute witness to expose Hill's hypocrisy.

Garrow successfully defends a man falsely accused of murder at a polling day riot. Approached by the victim's daughter Garrow agrees to find and prosecute the real murderer putting himself in grave danger from the man's colleagues and chief magistrate of the constabulary. Lady Sarah seeks documents to discredit Lord Melville and legally regain her son.
