 Driving while emotionally distraught, Helen Barton becomes distracted and strikes a pedestrian. She panics and flees to her parents  home, and her mother Irene decides to try to protect Helen by confessing to the crime. The evidence proves that Irene could not be the culprit, so Dan Mathews begins interrogating all of the family members. Hoping to somehow belatedly help the victim, Helen returns to the scene and a witness tells her that the victim has died. This erroneous information so upsets the emotionally fragile young woman that she becomes suicidal and threatens to jump off a nearby bridge. The usually gruff Dan Mathews must use guile, warmth, and psychology to dissuade her from taking her own life.
