Switched at Birth - Season 1

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.

In "American Gothic," conflict looms between the polar opposite mothers when Kathryn questions Regina's parenting style. In addition, Regina, Daphne's mother, refuses to join the Kennish's in their efforts to sue the hospital that made the life-altering mistake of switching the girls at birth, leaving Kathryn to wonder, what is this stranger hiding? As the girls struggle to adjust to life together, Bay, begins seeing Ty, a boy from Daphne's old neighborhood, while Daphne goes on a date with Liam, totally unaware that he's Bay's ex-boyfriend. While Bay may have met the one guy who can keep up with her rebellious ways, Daphne, unfortunately, realizes dating a hearing person may be more difficult than she had anticipated.

In "Portrait of My Father," now that Regina and Daphne have completely moved into the Kennish's home, many of Kathryn's friends and neighbors have begun asking questions. Kathryn decides it's best to keep their situation a secret and devises a lie, in an effort to protect Bay, who quickly becomes victim to town gossip. Bay asks Daphne more about her biological father, but is shut down, leaving her more determined to further investigate. Meanwhile, John gets involved in Daphne's basketball games, and it's there that he meets Melody, Regina's best friend and Emmet's mother, who also happens to be the school counselor and fill-in coach at Daphne's school.

Toby and his friend Wilke's band are excited to perform at the benefit, but they're in need of a drummer - can Daphne's deaf friend Emmett really play the drums? As the night goes on, Daphne is faced with a heartbreaking decision -- to choose between a family she barely knows and an exciting new love interest who makes her feel that being deaf is not an issue. Meanwhile, Melody and John appear to be establishing a bond during the benefit. As rumors fly about the family's real situation, Kathryn has a difficult time accepting her husband's new friend. Making matters worse, Regina accepts a dinner invitation from the ex-husband of one of Kathyrn's best friends.

Meanwhile, Daphne enrolls in the advanced cooking class at Buckner Hall where she soon realizes their kitchen does not cater to deaf people.

In "The Stag Hunt," Bay searches the internet and thinks she has found her birth father, Angelo, and asks Emmett -- who has been helping Bay try to find him -- and Daphne to go with her to meet him. When Daphne finds out that Bay and Emmett have been getting together to track down her birth father, she grows increasingly upset and maybe a little jealous that they kept this a secret. Even though she's angry with them, Daphne chooses to go in hopes of confronting the man who once abandoned her, but is this the right Angelo Sorrento?
