Not a Plan
If Ann and Ben don’t stop accidentally ruining each others’ birthdays, they’re not going to be best friends much longer. A joint party sounds like the natural solution, but that requires planning, and that brings up a whole host of issues and insecurities as Ann and Ben confront the fact that their lives aren’t exactly what they expected as they hurtle toward 30. This party is supposed to save their friendship, but will planning it destroy them?
