Haven't we all wondered if we had perhaps been switched at birth when we disagreed with our parents? Now how about if it turns out that the hospital actually did switch babies, purely by accident? And the families don't find out until the children are teenagers. Bay Kennish (played by Vanessa Marano from Without a Trace and the Gilmore Girls) has a high school project that includes learning about blood types and she inadvertently finds out her parents blood types do no match hers, showing she absolutely cannot be related to either of them. The family has their DNA tested and confirms the results Bay has come up with in school. Finding that the hospital made a huge error by mixing up the babies, they find the other child and discover how different her life is. Lea Thompson (Back to the Future Trilogy) is Bay's stay at home mom Kathryn and her father, John is played by D.W. Moffett (Friday Night Lights). Bay's new found sister is Daphne (Katie Leclerc from Veronica Mars) who unfortunately suffered deafness due to a case of meningitis as a young child. Daphne, her mother, and grandmother have a hard life and soon the Kennishes invite them to live in their guest house. Deaf actress Marlee Matlin also stars as friend of Daphne's mom, Regina.
