In the series premiere of this drama, a hospital error that involved sending two newborns home with the wrong families is uncovered years later, when the girls are teenagers. The girls went on to lead very different lives: Artistic Bay Kennish (Vanessa Marano) grew up in a world of privilege, while athletic Daphne Vasquez (Katie Lecleric) was raised by a single mother and contracted an illness that left her deaf at a young age.

Kathryn questions why Regina isn't joining in the lawsuit against the hospital. Meanwhile, Daphne goes out with Liam and encounters new difficulties dating a hearing person; and Bay finds a kindred spirit in Ty, who hails from Daphne's old neighborhood.
