Phil (Ty Burrell) has a new prospective client named Tad (Greg Kinnear) whom he invites to his home to talk about the house he wants to sell. Tad comes and he is extremely friendly to Claire (Julie Bowen) since he kisses her on the lips for hello and goodbye. Claire finds his move inappropriate while Phil does not mind about it telling Claire that it does not mean anything. Tad comes back the next day to invite Claire and Phil at his home and he continues kissing Claire. At his home, Claire sees that he kisses every woman that way, even the members of his family, so she can relax and enjoy Tad's jokes, something that Phil does not like at all.

Haley (Sarah Hyland) fibbed on her college applications claiming that she is a Big Sister and Claire and Phil forced her to join the Big Brothers Big Sisters organization. Now, she has to work as a Big Sister to her new "Little Sister" Annie (Alexis Fowlkes), something that she does really well causing Alex's (Ariel Winter) reaction. The two girls start fighting and Luke (Nolan Gould) interferes to make them stop and tells them that they were both bad big sisters to him. Luke's words make Alex and Haley to remember their old habits when they were younger and they were dressing up Luke, something that Luke is not happy about.

Meanwhile, Cam (Eric Stonestreet) and Mitch (Jesse Tyler Ferguson) have to stay with Jay (Ed O'Neill) and Gloria (Sofía Vergara) for few days because their house is being fumigated. This cohabitation causes some issues between the four of them.
