Phil (Ty Burrell) wants to build a treehouse for Luke (Nolan Gould) but he does not tell Claire (Julie Bowen) because he knows that she will say no. So, when he brings the supplies for it, he tells Claire that they discussed about it the previous week and they agreed. Phil starts building the treehouse with Luke's help, but Luke gives up on him after things are not going really well. Phil tries to finish the treehouse alone when his neighbor Andre (Kevin Hart) sees him and offers to help him.

Haley (Sarah Hyland) has an essay for her school with the subject "Biggest obstacle you had to overcome". She finds it difficult to find something to write about and she accuses Claire for that because they made her life easy and now she does not have anything to write about. Claire, after hearing Haley's accusations, tricks her and drives her in the middle of nowhere abandoning her with no money or phone to come back home. When she does, she tells her that she found her obstacle.

Gloria (Sofía Vergara) and Jay (Ed O'Neill) have Jay's friend Shorty (Chazz Palminteri) and his girlfriend Darlene (Jennifer Tilly) at their home for dinner. The two of them talk about romantic things they do, and Gloria does not miss the chance to say that Jay does not do anything of these things. Shorty and Darlene say they will go Salsa dancing and they invite Jay and Gloria to go with them. Gloria is excited with the idea but Jay refuses to go since he does not know how to dance.
