Will is a rising star in New York City architecture, managing a tough project and negotiating to join an important firm. He rarely smiles. His wife Catherine is on the rise as well, as the social engine of his success. They have a son, about eight. Will hits a bump when he meets Kate, a designer of smaller spaces whose work Will has seen (at his son's school). He recommends her for a project, neglects to tell her he's married, and sort of seems available. She falls hard, then meets Catherine and gets a job offer in L.A. Should Will sign with the big firm, go with Catherine on a dream vacation in the Caribbean, and wonder about Kate in L.A.? A flock of birds may hold the answer. While collaborating with an urban designer (Collins), an architect (Wilson) begins to second guess the perfect life he has constructed for himself and his family.
