The episode begins and Phil has a big announcement for the family. Thanks to a high-level real estate deal, he will get to use of an RV for the summer and is already dreaming of a family trip; perhaps to Yellowstone. Claire, knowing how the family really works, decides that Jolene (what Phil named the RV) is not going to work with three kids cooped up in it for hours and hours. But she decides to let Phil take them on a long drive just to prove she is right and so she wouldn't have to look like the evil parent. With the Dunphys gone, Jay and Gloria have a problem.
Manny needs his backpack that contains his works for the poetry reading he is attending in the night. Manny also needs to convince Jay and Gloria not to show up because he is going to go with some of his "darker" works. Cameron and Mitchell are excited for Lily being in a gymnastics meet, and she is quite good at it. So good, in fact that both Cameron and Mitchell are getting too wound up about it, to the point where Mitchell is actually rooting for another gymnast to fall off the balance beam. Which would have been fine, had not everyone heard it. Unfortunately, she does, and Lily moves into first place as a result. A hyper-competitive mother accuses Cam of fixing the hair on her daughter on purpose so the bun would come undone during her floor exercise and stop her from completing it.
Claire's plan for the kids going crazy in the RV is not really working. Luke thinks it’s too cold, but Haley is kind enough to loan him a blanket. Alex wants the music changed, so Claire tries to find something even worse. Alex ends up liking Claire’s choice even better. Still, Claire is unfazed. Phil has promoted the trip to Yellowstone to a cross-country trip and the kids think it is an awesome idea. Jay, Gloria, and Manny head over to Mitch and Cam's because Cam drove Luke and Manny home from school and Manny left his backpack in his car. They go in their house the same way they got into Phil and Claire's house. At Phil and Claire's house, Jay and Gloria felt the need to snoop around, read mail, check the medicine cabinet in the bathroom, and even have some brownies.
Cameron and Mitchell apparently had a party the prior night which Jay and Gloria weren’t invited to. There is even what looks like a drawing that insults them. They are quite upset and try to figure out why they weren’t invited. Jay accuses Gloria of being horrible at Pictionary, while Gloria accuses Jay of being hyper-competitive and always yelling at her. Actually, Manny is to blame. He had the invitation from Cam in his backpack and forgot to give it to Jay and Gloria. So he tries to sneak it into Cam's briefcase to shift the blame away from him. Only one problem: Gloria had already looked in Cam's briefcase, so she realizes the invite was just put there. Jay and Gloria can’t believe Manny was being sneaky and deceitful like that.
At the gymnastics meet, Cam and Mitchell are desperate to save face and overcompensate by cheering for Lily's competitors. Lily ends up bailing them out. Another gymnast falls off the balance beam and Lily rushes to her aid. She gives the girl a hug and takes the pins out of the girl's hair because they are hurting her. Lily wins the meet and gets to be on the team. In the RV, Luke swats at a bee that got in and accidentally slaps Alex. Then Haley tries to throw her drink at it and it hits Luke, who retaliates with the hose from the kitchen sink. The fight continues as another bee makes it inside and Alex's sweater gets ripped.
Phil pulls it over and goes berserk since Claire didn't stop the kids on purpose. While Phil calms down with a couple of other dads who are also in his RV situation, Claire and the kids feel a bit of guilt after seeing him flip out. Realizing Phil wanted to plan a big summer trip, Luke is suddenly worried because he is about to flunk pre-algebra and would have to take summer school. He didn't tell anyone because he felt even worse having followed genius Alex through school. Alex has actually been dating two guys at once, much to Claire's surprise and pride, but they both dumped her on the same day when they found out. She is quite embarrassed.
Haley tried out as a Laker Girl, and failed miserably. Claire, buoyed by learning all of this new information, goes out to tell Phil it was a great idea to take them on a summer trip. Being forced together actually made the kids bond. The proof of that is that fact that all three of them are doing Haley's Laker Girl audition. Phil is overjoyed on seeing this and joins the kids. At home, Alex teaches Luke some math, while Phil helps Haley with her Laker Girl routine. The episode ends at this point.
