Lena Fulvi has been arrested for the murder of her mother. She insists it was an accident, but she has been accused by a nurse in the hospital who saw her do the deed. Her sisters willingly testify against her. But the Inspector questioning Lena is not convinced that it is an open and shut case. He probes the pain and darkness that Lena conceals beneath a sophisticated veneer, embarking on a journey with her that changes them both.
