Based on a memoir, four siblings must learn to take care of themselves as their responsibility-averse, free-spirit parents both inspire and inhibit them. When sober, the children's brilliant and charismatic father captured their imagination, teaching them physics, geology, and how to embrace life fearlessly. But when he drank, he was dishonest and destructive. Meanwhile, their mother abhorred the idea of domesticity and didn't want to take on the work of raising a family. Features  Brie Larson, Woody Harrelson, and Naomi Watts.
