The family is in the throes of summer activities: Phil and Claire are trying to orchestrate a kid-free week by coordinating Luke's camp with Haley's beach trip and Alex's volunteering excursion; Jay and Gloria are getting Manny ready for his first solo trip back to Colombia; and Mitch and Cam make it a summer to remember.
Luke and Manny have their first day at high school, which proves to be harder for Phil and Gloria than for the boys. Elsewhere, Claire makes her big return to the workforce at Jay's closet company and is a little rusty on her first day, and Cam starts a new substituting gig at the high school, leaving Mitch to try to juggle Lily's first day of pre-school and a very important meeting at work.
Phil seems to have found his wheelhouse in real estate - recently divorced women - but it's taking up a lot of his time. Meanwhile, Luke invites his buddies over for a high-stakes poker game in the basement; Gloria think baby Joe might be cursed; and Cam holds an elaborate pet funeral for Larry the cat's made-up wife -- all for Lily's sake.
Cameron's older, single sister Pam is coming for a visit, and Cam is in a panic to hide the engagement until he can delicately break the news to her, but it turns out she has news of her own. Phil and Claire make a joint, guilt-ridden decision to miss one of Luke's volleyball games - that is - until one of them goes behind the other's back, and Gloria is in denial that she might need reading glasses.
Jay pulled a lot of strings to get reservations at the hottest new restaurant for a family adult's night out. Unfortunately, in each household everyone is running late - Gloria is taking forever to get ready per usual, Claire and Phil get in a tiff about letting Luke stay home alone, and Mitch and Cam end up putting on the same outfit
When Gloria hires a too-good-to-be-true male nanny, Jay and Manny are pretty much dead set against it. Frank is in town and feeling a bit lonely recently, so Phil and Jay take him out to help get his groove back. And, Mitch and Cam commission Pepper to plan their dream wedding, but Pepper might be dreaming a little too big.
The family attends the annual school fair and Phil has a big 20th wedding anniversary surprise planned for Claire at the fairgrounds, but unfortunately, she simultaneously has a surprise for him back at home. Gloria signs Jay up to be a fair cop for the day and it gets worse when he's partnered up with his nemesis. Elsewhere, Mitch, Cam and Lily try to enjoy the fair but Cam is in a funk from the football team's recent losing streak, and Haley has an awkward first encounter with Andy.
-- I Want To Know What Love Is
With some urging from Claire, Jay begrudgingly agrees to return to ClosetCon this year, and things get interesting when Jay is reunited with some old colleagues. Cam takes Mitch and Lily to the Tucker family farm for the first time and is excited to fold them into country life, that is until Grams pays an unexpected visit. And back at home, Phil, Gloria and the kids get into some mischief involving Jay's very delicate Apollo 13 spacecraft model.
With a big football game coming up and a record to break, Coach Cam is intensely focused and showing no mercy even when the opposing team is playing with an unexpected disadvantage. Elsewhere, Claire is determined to prove to the staff that she is more than just the boss's daughter, and Phil tries to teach his kids a lesson about optimism, but the universe just isn't cooperating.
Jay takes Manny out to cut down their own Christmas tree, and Gloria is on edge with mom in town, but changes her tune when she sees her bonding with Claire. Elsewhere, Mitchell is forced to do last minute shopping when they didn't get Lily the right gift, and Cameron takes Lily to a charity event where they experience the true meaning of Christmas.
