Based on a true story,[1] the film stars Patty Duke, Tracey Gold, David Ogden Stiers, Gabrielle Carteris and James Brolin.
Her doctor reveals to Beth that Lori is in urgent need of a donor, though her rare blood type makes finding one a difficult task.
After a period of time without finding a donor, during which Lori's health worsens, Beth realizes that only confronting a dark secret from her past can save her daughter: when Beth was eighteen years old, she was set to marry a young man named Greg Hollander, and shortly after found out that she was pregnant.
She later decides, though, that she wants to do all that she can to help save a woman's life, and agrees to be Lori's donor, though she makes clear that wants nothing to do with Beth.
What Beth has been fearing for years is now reality: After a test, it turns out that her husband Ken Bradfield is not Lori's father.
