In the living room, Lori and Leni are looking at their phones. Lori is pleased at the fact that her selfie photo has 100 likes. Suddenly, Leni informs Lori that Carol Pingrey has a selfie has 101 likes. Lori is unhappy about this, since Carol has a reputation of one-upping Lori in nearly everything she does which is shown in numerous flashbacks including Carol selling the most cookies, becoming prom queen, and winning a golf tournament. Not wanting to be one-upped by Carol again, Lori makes it her mission to have a selfie that'll get more likes than Carol's.
First, Lori tries to take a selfie in the bathroom, but gets interrupted by Lana, who was making adjustments to the toilet. Later, Lori attempts to take a selfie outside, but runs into numerous problems with her siblings (with Lynn hitting her with a baseball, getting hit by Lily's dirty diaper when Lori refuses to change her, falling into a grave Lucy dug up and getting hit by Lincoln's RC helicopter). Needing a way to get her siblings out of the way, Lori tries to encourage the siblings into doing yard work, which causes the siblings to leave. With the siblings finally gone, Lori manages to take a successful selfie that gets 102 likes. However, not long after posting it, Leni reveals that Carol released a selfie with a corgi in it. Not wanting to take the loss again, Lori tries to take a selfie with the pets. Lori ends up getting mauled in the process, and enlists Lola's help into touching the photo up when the initial photo has the pets attacking Lori. Lori is satisfied with result until Leni reveals yet again that Carol posted another selfie, this time, hanging out with her friends at a café. Lori enlists Lincoln, Leni, and Luan into helping her with her café selfie, and manages to take a successful shot.
Suddenly, Leni reveals that Carol uploaded a selfie with her boyfriend on a picnic. With blind determination in her eyes, Lori calls up Bobby to meet her at a rest stop to have a picnic, despite having a dentist appointment at the same time. At the rest stop, Lori attempts to make the scene look romantic as possible, but when Bobby reveals that he had his wisdom teeth removed, Lori, touched that Bobby went through so much, decides to forget about upstaging Carol.
At the mall, Lori is trying to return the picnic stuff she bought, when suddenly, she sees Carol shopping. Suspicious, Lori walks up to Carol, and admits defeat, saying that she shouldn't be jealous that she's better than her. Carol, however, admits that she was actually jealous of Lori, since she thought she was better than her. Realizing that their constant bickering was all for nothing, Lori and Carol admit that they're not as bad as they thought, and decide to take a selfie together, establishing their newfound friendship.
The next day, Leni reveals that two girls named Bianca and Sooyoung have taken a selfie that has more likes than Lori and Carol's. Carol immediately calls up Lori, and the two begin planning on fighting back against Bianca and Sooyoung.
