Charlie and Hannah were best friends in high school, bonding over suburbia punk-rock pipe dreams and middle-class teenage angst. In love with each other but never bold enough to say it, the pair jokingly made a pact that if neither were married by the time they turned 30, they’d be together. It was a promise. Now, years later, the pair have fallen apart. Charlie lives in LA and is failing at his backup plan turned career as a personal trainer. When he sees Hannah on a trip back home to meet his niece, the two pick up right where they left off and drunkenly decide to go through with their old marriage pact. So Hannah moves to LA with Charlie and they live happily ever! Oh, wait. Hannah gets to LA and the two realize they don't know each other at all anymore. Not only are Charlie and Hannah, not in love, they don't even like each other. But Hannah, running from her past and Charlie, desperate to not fail again, decide to try and make it work.
