Pioneering eighteenth century barrister William Garrow returns to the Bailey to champion the rights of prisoners. Based on the true story of James Hadfield - accused of attempting to assassinate King George III - Garrow risks his reputation to defend the indefensible. And he changes British law forever.

Garrow is confronted with an impossible choice: to expose British colonial brutality in open court, or to re-unite Lady Sarah with her son. The dangerously ill Southouse intervenes, and Garrow is forced to decide. Love or honour? It cannot be both.
