Harriet Smith (Academy Award nominee Pauline Collins - Shirley Valentine) forges ahead as Britain's Ambassador to Ireland, one of the country's most coveted - and potentially explosive - Embassy posts. Supported by her Commercial Attache and MI6 operative John Stone (Denis Lawson - Bleak House), Harriet uses both diplomatic skill and common sense to bravely face issues ranging from territorial disputes, kidnapping and cults to sabotage and murder. Continually under fire, the Ambassador treads a minefield of Anglo-Irish tensions as she strives to prevent her personal life from clashing with her professional career - and her duty to Britain.
