Bay Kennish discovers during a biology class that she has a rare blood type which is different from her parents. Intrigued by her new discovery, Bay convinces her parents, Kathryn and John, to visit a genetic testing facility where it’s confirmed that Bay is not their biological daughter. There was a mix up at the hospital and both families took home the wrong babies. Days later, the Kennishes are introduced to their biological daughter Daphne and her mother Regina Vasquez. The Kennishes are surprised to see that Daphne is deaf. John and Kathryn immediately research ways to help Daphne and suggest the possibility of Daphne attending Bay’s private school, which doesn’t sit well with Bay. Regina is against Daphne attending the school but agrees to move her family into the Kennish house to deal with their new family situation.
