When Dave Johnson and his family arrive from Michigan, they're unfazed that their new dream home is located in a community quite different from their previous small town. However, their opinionated next-door neighbor Calvin Butler is wary of the newcomers, certain that they'll disrupt the culture on the block. Dave realizes that fitting in with the new community is more complex than he had expected, but if he can find a way to connect with Calvin, there's an excellent chance of making the new neighborhood a great place to live.

When a water pipe bursts at the Johnsons' home, Calvin reluctantly agrees to help Dave repair the damage; Gemma discovers a surprising secret about her new neighbor, Tina.

Concerned about the safety of a treehouse Calvin's building for Grover, Dave recruits Marty to supervise covertly; an innocent mistake on Malcolm's part leads to a heated bake-off between Tina and Gemma.

As Halloween draws near, Calvin tries to determine what's behind the sudden strange occurrences at the Butlers' house; Gemma and Tina question if their days of sexy costumes should be behind them.

When Tina and Gemma get more than they bargained for in a revealing art class, Calvin can't hide his jealousy and takes drastic action; Dave, Marty and Malcolm team up to crack the case of an unfinished mystery novel.
