When everyone but Calvin accepts Dave and Gemma's invitation to their housewarming party, Dave decides he's finally had enough of Calvin's refusal to welcome him to town.

One year after the Johnsons moved next door to the Butlers, Dave is eager to take on a bigger role in Calvin’s annual Yardecue and prove how much a part of the community he’s become. But Calvin’s reaction makes it clear that, while the relationship between the two families has grown, the friendship between Calvin and Dave still has a way to go.

A near-accident awakens Dave's sense of civic duty, prompting him to team up with Calvin to try to improve the safety of their community; a trip to the county fair turns into a nerve-racking adventure for Malcolm, Marty and Grover.

Calvin weighs the pros and cons of making a major life change; Marty turns to Dave for help dealing with a troubling discovery.

Calvin and Tina are looking to remodel their home when they uncover discriminatory processes with their bank's appraiser. Meanwhile, Marty asks Trey for fatherly advice on co-parenting with Courtney.
