A one-hour scripted drama, "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 working class neighbourhood. Despite overwhelming socio-economic and ethnic differences, both families must learn to co-exist as parents and blend their lives into one for the sake of their daughters.
