La fille inconnue

One evening after work hours, Jenny, a young doctor, allows the door buzzer at the small clinic where she works to go unanswered. It's only later that she learns that the person ringing was an unidentified African woman found dead shortly after by the side of a road. Consumed by the thought that she is to blame, Jenny embarks on an obsessive crusade to discover who the anonymous woman was and to see to it that she is not forgotten.
