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.

Gloria is excited at the possibility for being selected for jury duty; Claire brings Alex and Haley to work and hopes to impress them; Phil takes Manny and Luke's class to community service day.

With Closet-Con right around the corner, Claire is on high alert and convinced there is a mole in the company. Meanwhile, Phil goes vigilante when he and Gloria confront Auntie Alice for stealing her hot sauce recipe. Jay tries to teach Joe how to do some manly handy work, and with prom coming up, Mitch helps Luke with his "promposal" while Cam helps with Manny's, but Cam goes a little overboard, revealing that there maybe something deeper going on.

Jay does not want to give the new family moving in across the street the wrong impression and goes out of his way to make sure they know he is the best kind of neighbor, while Manny decides that the best way to an attractive and radical-thinking teenage girl's heart is through his actions. Meanwhile, at the Pritchett house, the entire family is using Alex's recent bout of mono to their advantage. Finally, Cam and Mitchell have always felt they were the most open, non-judgmental and supportive parents. However, when they overhear Lily insulting her new friend, they have to take a quick look in the mirror before they teach her a lesson about acceptance.

Fearful that the romance between him and Claire is fizzling, Phil calls upon his altar ego, Clive Bixby, to get Valentines day back on track. Meanwhile, much to Gloria’s chagrin, Jay shows a bit of child favoritism when they must deal with Joe’s inappropriate Valentine gift-giving and Manny’s dating indecisiveness. When Cam and Mitch try to empower Lily, Haley and Sal to stand up to the men in their lives, things don’t turn out as planned. Finally, Alex discovers she has a secret admirer who may be a little too involved with family.
