Maddie and Ben have been dating for nine years. They know each other inside and out, a relationship marked by contentment and affection, seeing their commitment to one another as a "valid life choice," something they proclaim often - and often loudly. Maddie's younger sister, Mia, has been dating Casey for seven weeks. With a shared c'est la vie attitude, Mia and Casey are smitten with each other, and thrilled to explore the oh-so-many things they don't know about each other yet. But when they announce they're getting married and having a baby, it's news that throws Maddie for a loop. Surprisingly, the girls' parents, Vicky and Joel, couldn't be more pleased. Married 35 years, they have recently adopted a carpe diem sort of philosophy, rather like Mia's, cptfc maybe because they're getting older and lost a good portion of their savings when the economy tanked. With three very different relationships tightly intertwined in one family, will it be free thinkers vs. over-thinkers, or will each couple begin to see things a little bit differently?
