In 1979 Santa Barbara, California, Dorothea Fields is a determined single mother in her mid-50s who is raising her adolescent son, Jamie, at a moment brimming with cultural change and rebellion. Dorothea enlists the help of two younger women – Abbie, a free-spirited punk artist living as a boarder in the Fields' home and Julie, a savvy and provocative teenage neighbour – to help with Jamie's upbringing.
