Based on the real-life diaries of Adèle Hugo, The Story of Adele H. is a psychological drama opening in Halifax, Nova Scotia, in the 1860s. The daughter of famous French writer Victor Hugo, Adèle (Isabelle Adjani) has left her father's home to seek out her fiancé, the English soldier Lt. Albert Pinson (Bruce Robinson). She conceals her identity and rents a room in a boarding house from Mrs. Saunders (Sylvia Marriott). Pinson wants nothing to do with her, but she still obsessively follows him and spies on his affairs. Spending her time writing madly in journals and letters, she eventually meets the bookseller (Joseph Blatchley), who develops an interest in her. Her madness grows when Mrs. Saunders discovers her true identity, and even more so when the bookseller gives her a copy of her father's latest work, Les Miserables. When Pinson is transferred to Barbados, Adèle follows him again and sinks into insanity, living on the street. With the help of a local woman, Madame Baa (Madame Louise), Adèle returns home to her father and spends the rest of her days writing in her diary in Paris.
