As Astrid and James prepare to celebrate a special occasion, their ‘hook-up-aversary', all that stands between them and a much-needed night together is getting their kids to bed. From a pillow fight turned too rough to a baby that will not sleep, their simple plan of re-watching the bad movie that first brought them together is thrown into jeopardy. When Astrid's sister's husband, Bo, shows up at their door following a fight with his wife, it quickly becomes clear that this hook-up-aversary will not be anything like they planned.
