Dominic West and Michael Fassbender star in this four-part historical drama set in the mid-17th century depicting the turbulent events of the English Civil War through the eyes of 17-year-old Angelica Fanshawe (Andrea Riseborough). As the country is plunged into chaos and Oliver Cromwell (West) and his army threaten to overthrow King Charles I (Peter Capaldi), young aristocrat Angelica is brought close to the key figures in both sides of the conflict.
