Saul, a sculptor and professor of art in a small Pennsylvania town, believes he has a beautiful marriage until his wife Ruth decides that the family needs therapy. What happens after that, as seen from the separate points of view of Saul, Ruth, and their son Jesse, is an explosion of anguish and liberation, growth and pain, as each character, trapped in the bubble of their own perception, wrestles with a love that turns to hate and the moral divide between self-interest and compassion.
