Mingo helps Daphne organize a fundraiser for a sign language school in Mexico; and Bay is livid after a student sells crude T-shirts using her artwork. Elsewhere, Regina faces the consequences of digging through Eric's past.

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.
