Brett and Michelle (Mark Duplass and Melanie Lynskey) are struggling to rekindle the spark in their relationship, which has puttered out from the stresses of marriage and children.  When Brett's friend Alex (Steve Zissis) and Michelle's sister Tina (Amanda Peet) move in with them, the foursome engage in a tragically comedic struggle to follow their personal dreams while still remaining good friends, siblings, and spouses to each other.
