Natalie Dormer leads a cast of British actors in this gripping 18th century drama, detailing the scandalous life of Seymour, Lady Worsley, who dared to leave her husband and elope with his best friend, Captain George Bisset, played by Aneurin Barnard. The passionate, courageous Seymour, Lady Worsley, escapes her troubled marriage only to find herself at the centre of a very public trial brought by her powerful husband, Sir Richard Worsley, played by Shaun Evans, who seeks compensation from her lover for the affair.  As this extraordinary true story unfolds, Lady Worsley takes the brave decision to publicly expose the secrets of her marriage.  The scandalous courtroom revelations challenge the hypocrisy of the law that brands a wife the property of her husband, calling into question the whole concept of a woman's 'worth'.
