Happily married couple Kelli and Oliver Weston are living the old adage "marry your spouse, marry their family" as they spend their weekends visiting their respective in-laws and learning to maneuver through the idiosyncrasies that make up every family. With each visit, Kelli and Oliver do what they can to keep the things on an even keel despite their very different backgrounds. In the premiere episode, Oliver installs a nanny-cam at his home so he can keep an eye on the babysitter while he takes Kelli for a night out. But when the babysitter has a visitor, suddenly it's Louis and Jason who are glued to the screen. Meanwhile, Ricky thinks Kelli is abusing her children after she sees a drawing her granddaughter made.

It's Dani's birthday, and everyone thinks Oliver is going to ruin it because he always ruins birthdays. Kelli buys Dani a psychic visit as a present. And Shawni (recurring guest star Collette Wolfe) becomes convinced she is adopted.

Ricky plans on throwing out Oliver's childhood couch, but both he and Jason are ready to fight for it. Claire panics when Louis brings home a piece of art that features her in the nude.

Gil's aunt dies, but nobody liked her until they find out she was leaving behind a potential fortune in her will. Oliver and Kelli scramble to find a way out when Shawni asks them to be her horrible son's guardians.

It's Ricky's annual summer Christmas photo, but Louis scheduled his company-mandated life insurance physical at the same time, and a representative will be dropping by to take a urine sample. Since Louis smoked pot with Blake last week, he's now on the hunt for an untainted sample.

Gil is up for an award at his college, but after Jan and Kelli find out he's not going to win, they try to stop him from going. Dani comes home super high from a wild night. And Shawni wants Enzo (guest star Adrian Gonzales) to propose.

The Weston family members experience individual traumas as they go through the five stages of grief: denial, anger, bargaining, depression and acceptance.

Oliver finds Blake and Dani naked and has to get them of the house before anyone finds out. Shawni takes Kelli's old jean jacket and won't give it back. And Enzo helps Gil craft a letter to the "permit fascists" at the farmer's market.

Jason tells Kelli he got a drunken vasectomy, but Claire has some shocking news of her own. Blake brings a girl home by pretending he's an Australian pop star. And Ricky and Louis celebrate their anniversary.

To mark their 10-year wedding anniversary, Oliver and Kelli are renewing their vows at the Durnin residence, but Oliver is worried about saying his vows. Gil and Jan are bitter that Louis and Ricky excluded them at their country club during their kids' wedding. Dani and Blake start dating again. And Claire pesters Shawni about the time she and Jason slept together.
