When a high school chemistry lab leads to privileged teen Bay Kennish (Vanessa Marano) learning that she was accidentally switched at birth with Daphne Vasquez (Katie Leclerc), a working-class teenager who became deaf when she was three, their opposite worlds collide, changing the girls and their families’ lives forever.

Perhaps no one got between them more than Emmett Bledsoe (Sean Berdy), Daphne’s motorcycle-riding best friend, who quickly falls for Bay.
