After Dre and the kids question Bow’s unusual upbringing, we flashback to a young, 12-year-old Rainbow living in a commune with her family. When the commune is unexpectedly raided, they are upended and must move to the suburbs. The mixed-race family has difficulty acclimating to this new mainstream life, and the kids struggle with their biracial identity as they try to fit in at their new school.

Dre and Bow start to slip on the kids' activities and chores around the house, so Bow persuades Dre to hire a nanny. After several interviews that don’t go well, they meet Vivian, who impresses them with her desire to take care of the whole family, including Dre and Bow. Dre struggles with the idea of hiring a black nanny, but decides to give her a try. Meanwhile, Diane decides to run for class president, so when the smart and bubbly Susie Kwest becomes her competition, Zoey helps Diane create a smear campaign to win Diane the vote.

Dre has always felt his older son was never like him, but when he finally meets Junior’s cool friends, Dre is all in and happy that his son may have the opportunity for an actual social life. Meanwhile, Bow is dealing with Ruby, Zoey, Jack and Diane not confessing to things breaking around the house and decides to handle it her own way after some judgment from Vivian.

Dre decides to take his family to Walt Disney World on the magical, first-class vacation experience he was never able to have as a kid. With the help of a VIP tour guide, Dre and the kids take full advantage of their VIP status. Meanwhile, Bow, Pops and Ruby set off on their own adventure at Walt Disney World.

When Dre discovers that Zoey is questioning her belief in God, he undergoes a crisis of faith and leans on family members and coworkers for their input. Meanwhile, Bow’s brother Johan comes to stay with The Johnsons after living abroad and becomes an instant thorn in Dre’s side.

The Johnsons go to Jack and Diane’s school play about Columbus Day, and Dre is dismayed by the historically inaccurate way that the holiday is portrayed. He feels like there aren’t enough black holidays, so he enlists Aloe Blacc at work to help him create a catchy song to raise awareness for a holiday worth celebrating, Juneteenth.

Ruby gets scammed and Dre begins to suspect that she isn’t as sharp as she used to be, particularly because she was the one who used to scam other people. Zoey’s friend Aaron visits and Diane develops an instant crush on him.

Dre brings everyone together for a rowdy family game night and the competition is fierce. The game of choice is Monopoly and as the night progresses, alliances are formed and some are pushed to their limits. Meanwhile, Bow makes it clear how she feels about Junior’s girlfriend, Megan.

The family is divided over the idea of getting a dog after Dre and Bow promise Jack they can get one after he gets Straight A’s – and he does! Meanwhile, Bow’s brother Johan is in town and he doesn’t get the warm welcome he expects from Ruby.

Dre underestimates how hard of an adjustment operating during a pandemic will be for the Johnsons. Meanwhile, Junior’s attempts to bring his girlfriend closer to the family are stymied by the new realities of social distancing.
