As the holidays approach, Bay bristles at Kathryn's festive holiday spirit, complete with homemade peanut brittle and Christmas karaoke, while Daphne is frustrated with Regina's usual tradition of movies and Chinese food for Christmas. Then, after a joint family dinner including "magical" garlic knots, they wake to discover that the switch never happened. In this alternate life, Bay is an Olympic hopeful and Daphne is a successful artist with an upcoming exhibit. Is it the Christmas miracle they've always wanted? Could they even get back if they tried?.
Switched at Birth tells the story of two teenage girls who discover they were accidentally switched as newborns in the hospital. Bay Kennish grew up in a wealthy family with two parents and a brother, while Daphne Vasquez, who lost her hearing at an early age due to a case of meningitis, grew up with a single mother in a poor neighborhood. Things come to a dramatic head when both families meet and struggle to learn how to live together for the sake of the girls.
