While driving home from his law office in a rainstorm, Roger Whitwood brushes a drunk in the road. As he drives the soaked man to a shelter, he learns Bert has his daughter's blood type. Later, Roger is forced to look Bert up again to get blood when his daughter is in a serious auto accident. A friendship develops between Bert and Roger's family that includes Tad, a boy Bert has been watching over on the streets. At Roger's urging, Bert begins working to restore his self-respect and get off the street. Roger's point of view is altered also, and he begins to take pro bono cases to help people like Bert. Roger's daughter, Sharon, sees a need to help others also. Her attempt to befriend a woman and her small children gets her kidnapped. Bert uses his forgotten skills as a private investigator to find Sharon and arrange her rescue, but is seriously wounded during the rescue. His recovery, assisted by his landlady, results in a romantic relationship. Bert would like to adopt Tad, and so would Roger and his family, but, when Tad's mother shows up unexpectedly, his life is turned into turmoil. Where will Tad end up?
