When Lina dies, her ashes are to be scattered in the wind under her favorite tree. At the cemetery, her son Henrik finds a bouquet of flowers with the inscription: I love you for all time, Henning. Henrik becomes an investigator. He begins to search through his mother's estate for the secret life she led and discovers photos, love letters, and farewell notes from a Lars and a Henning. Who is Lars? Who is Henning? Henrik's mother never spoke about past relationships with men in the family, nor about her adoption and biological father. Henrik travels through Sweden following Lina's traces and discovers a different woman than the one he knew as his mother. Gradually, a chasm opens up. His mother becomes more and more of a mystery to him.
