When Tom and Sarah discover that their parents have been spending time at Connor's house and not theirs, jealousy rears its ugly head. But when it looks like there might be more grandparent time for everyone, they learn to be careful what they wish for.

After upsetting Marina, Tom tries to help out more around the house. While Sarah tries to find temporary employment, she and Denise worry their son will be corrupted after Kelvin decides he wants to learn all about Uncle Connor's business.

Connor invites the siblings to a party he’s throwing for his ex-wife, Emily. While he feels the need to prove that he is cool with their divorce, he is not the only one in the competitive spirit. Tom and Marina try to prove to each other that they still have game, while Sarah finds the perfect solution to the fact that she’s a bad gift-giver.

The family gathers to try and celebrate their parents’ anniversary without spoiling it — like every other year. However, after everyone learns what Tom’s new novel is about, the celebration may just be the worst one yet.
