A young woman's search for her biological family opens up a mystifying twenty-year old cold case of a mother and her baby daughter disappearing while on a walk, a development that arouses interest and surprise from a couple of television programs, local and federal law enforcement, and a splintered family. Dorothy had always felt the love of being raised by coddling well-off parents, and was encouraged by the death of her mother to cancer to take college classes towards a medical career. However, after a class lab experiment leads to her overhearing her father revealing that she was actually adopted, Dorothy decides to research the truth of her biological family by reaching out to a television docuseries focused on reconnecting families. A DNA test seems to lead to a close sibling match, but when Rory, the host of the docuseries, reaches out to the match, the young man, Scott, responds by telling him that his sister was not put up for adoption, but had disappeared with his mother when they went for a walk twenty years ago, a case that is now the attention of an episode being produced by another television docuseries. The reappearance of a woman who disappeared as a baby brings both television productions together into a collaboration, as the FBI joins the local police into the reopened case, but Dorothy wonders about the wounds of disconnecting with the father who raised her, reconnecting with a family who had lost her, as well as the mystery of what happened to her real mother.
