Andrew Buchan (Cranford, The Fixer) returns as fiery barrister William Garrow in this award-winning courtroom drama set in 18th-century England. In a time when prisoners in court have few rights, Garrow leads a legal revolution, coining the phrase "innocent until proven guilty" and defending the accused against the State. In return, he makes powerful enemies in politics and law. Chief among them is Sir Arthur Hill (Rupert Graves, Sherlock, The Forsyte Saga), now Assistant Secretary to the Admiralty. Jealous and vengeful, Hill wrongly believes that Garrow is involved with his wife, Lady Sarah (Lyndsey Marshal, Rome, Being Human). As Garrow tackles difficult and controversial cases, all drawn from the Old Bailey archives, Sir Arthur's net tightens around him. Soon Garrow is on trial, charged with "criminal conversation"--18th-century code for adultery. Can his friend and mentor John Southouse (Alun Armstrong, Little Dorrit, New Tricks) save Garrow's reputation and career? 4 episodes, 4 hours, 2 DVDs, SDH.
