In 1720 the eminent man of letters Daniel Foe is approached by Susan Barton, lately a castaway on a desert island. She wants him to tell her story, and that of the enigmatic man who has become her rescuer, companion, master and sometimes lover: Cruso. Cruso is dead, and his manservant, Friday, is incapable of speech. As she tries to relate the truth about him, the ambitious Barton cannot help turning Cruso into her invention.
