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.
