From a crowd of onlookers, one person steps forward to help. A teenage girl named Maddie walked to a highway overpass and stopped. As dozens of cars sped past, she climbed a railing, looked over the edge and considered stepping off. A few cars stopped then and people began to gather, but only person, David Johnson, sat down and talked to Maddie. That conversation led to a scream, a laugh and eventually a hug. This is the story of how someone was saved and someone else was changed. We also speak with Martha Thomas, the mother of a young woman who took her own life and the co-founder of an organization called “The Defensive Line.”
