Adam, Duke Ashton, who miraculously survived a shipwreck, does not remember anything - neither the fact that he has a ducal title, nor the fact that he owns vast lands - and is forced to rely in everything on the golden-haired beauty Mary, who nurses him, calling him himself as his legal wife. But is she really his wife? Sir Ashton begins to be overcome by doubts. However, he feels in his heart: Maria cannot deceive him and truly loves him - passionately, tenderly, to the point of pain and self-denial.
