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.
Calvin reluctantly agrees to let Marty create a website for his auto shop in hopes of drumming up more business; Dave makes it his mission to prove to his son that there's more to life than his favorite gadgets.
When the Johnsons' Christmas present for Grover is stolen, Calvin and Dave team up to recover the gift in time for the holiday; a nostalgic Tina tries to get into the Christmas spirit by reviving traditions from when Malcolm and Marty were kids.
Dave's patience is tested when Gemma's freeloading sister suddenly shows up with plans for an extended stay; Calvin grows frustrated that Malcolm is still living at home.
Tina spends time with the charming new minister she helped select for her church; Calvin suspects the man may be coveting more than just job security; Marty gets a surprise when he finally meets his disruptive, new upstairs neighbor.
