When Luke goes missing after a night out in a sketchy neighborhood, Manny, Phil and Gloria team up to track him down. Meanwhile, Haley is desperate to land an interview with the creator of a popular lifestyle website and interrupts Alex during one of her college classes. Alex’s professor, Arvin Fennerman, then proceeds to try and give Haley a piece of his mind.

Haley’s brilliant astrophysicist boyfriend comes to meet the family, setting Claire and Phil off in a competition about which one of them is smarter, making Alex feel self-conscious about her dim but handsome firefighter boyfriend, Bill. Mitch and Cam go on a yoga retreat, but when Cam finds out his dream team, the Kansas City Royals, is having spring training next door, he can’t resist sneaking out.

Haley meets Arvin’s parents but when things don’t go as planned, fate leads to an unexpected reunion with all of her ex-boyfriends. Meanwhile, the family seizes on a nursing home visit with Jay’s mean sister, Becky, to settle old scores. But as Jay, Claire and Mitchell compete for her time, Phil, Cam and Gloria end up getting trapped in the home’s basement with no way out.

Jay is hosting a Super Bowl party, and Claire is hosting a baby shower for Haley; both at Jay’s house. What could go wrong?

Dylan and Luke are really impressed with Bill’s tales of heroism and survival as a firefighter, which make Phil feel emasculated. To impress the guys, he invites them over for a little male-bonding moment that goes terribly wrong.

Phil pays a visit to his dad to make sure he is ok after hearing some concerning news about him. Meanwhile, Jay gives Claire and Mitch a bunch of their old childhood memorabilia that triggers them to reevaluate a long-held story about their first family vacation.

Mitchell is having a hard time letting go of his old life and Gloria steps in to help him say goodbye. Meanwhile, Haley, Luke and Alex decide to throw a party at the Dunphy house when Claire and Phil leave for a trip, and Dylan’s mom takes the twins for the night.

The entire family discovers saying goodbye is much harder than it seems.
