The joys and pitfalls of growing up are seen through the eyes of a child named Mason (Ellar Coltrane), his parents (Patricia Arquette, Ethan Hawke) and his sister (Lorelei Linklater). Vignettes, filmed with the same cast over the course of 12 years, capture family meals, road trips, birthday parties, graduations and other important milestones. Songs from Coldplay, Arcade Fire and other artists capture the time period.
