Annie is furious about Jake's inability to commit just as he's about to ask her to marry him.

Jake and Annie get a haunted house ready for the children in their building but run into trouble with one of the mothers. Dennah decides to wear a skimpy costume to an exclusive party.

After a rousing night out, Annie and Jake deface a sign at their building and find themselves embroiled in a hate-crime investigation in their building. Meanwhile, Gil, Dennah and Kay compete for the one remaining “plus one” spot on the wedding guest list.

Annie discovers that she was born in Canada and is not a US citizen. As her family and friends help her to revise for a citizenship test, Jake takes over responsibility for planning their wedding.
