Stacy Halloran has lived most of her life in 1950s-era housing development Arboria Park. But her beloved neighborhood may not survive much longer. Despite her parents' entreaties to 'stay in the yard where it's safe,' the Park is where young Stacy roams in quest of 'real life.' Through her wanderings, she learns about the area's agricultural history; meets people from backgrounds different than her own; watches her siblings develop interracial and same-sex relationships; helps launch the local punk-rock scene; and finally, settles as a wife and mother. As the neighborhood declines (along with her relationship with her mother), Stacy considers moving on to rescue herself and her daughter. But then a massive highway project threatens the ever-resilient Park - and it's Stacy's task to rally family, friends, and neighbors to save it.
