When their beloved sister passes away, Sylvia and Helen Rubinstein are unmoored. A misunderstanding about apple cake turns into a decade of stubborn silence. Busy with their own lives --- divorces, dating, career setbacks, college applications, bat mitzvahs and ballet recitals --- their children do not want to get involved. As for their grandchildren? Impossible. THIS IS NOT ABOUT US is a story of growing up and growing old, the weight of parental expectations, and the complex connection between sisters.
