Documentary filmmaker Mylène Moreno recalls her experiences growing up as the daughter of immigrants in California’s Orange County and returns to see how much things have changed since she left.  Once regarded as a wealthy, white, conservative enclave, Orange County is becoming less predictable, less tidy, more diverse, more interesting.  In a word:  Mexican.  Moreno follows a fierce battle against a controversial immigrant rights activist and discovers as much division within the Latino community as between the traditional establishment and the county’s increasingly vocal newcomers.
