Heartbroken, Nancy concentrates on her work and avoids intimate relationships. Hope, the daughter Nancy gave up for adoption twenty years earlier, finds her. A bond blossoms between them but is challenged by Hope’s leukemia. Hope needs a bone marrow transplant, but she has a rare blood type. Nancy is not a match. Nancy is determined to find Skip, Hope’s biological father, who never knew about Nancy’s pregnancy or why she disappeared so mysteriously.
