The Quads get an unexpected visit from the news crew one day, who ask if an actor named JT Steele is staying at their house. Dawn denies the accusations, as she has no knowledge of his whereabouts. Tom makes them leave by trying to advertise Get Sporty, and all seems good until Anne and Tom walks in, and that “Tom” is actually JT Steele. Excited by his appearance, the quads are eager to tell their friends that he’s at their house, however JT demands they keep his location a secret, in order to accompany the role of a typical suburban father. Tom and Anne leave the children with JT while they go to his luxurious condo for a while. Things begin to go awry in the Harper household when JT sends the children to school with $400 and brown-bagging their lunch, making the quads suspicious, and it gets increasingly difficult for the quads to keep their secret. When Nicky, Ricky, Dicky and Dawn suggest to JT about hosting a barbecue with a few friends, he seems opposed to the idea. Dawn accidentally breaks JT and makes him consider quitting being a dad and an actor (“dacting”) by saying “you don’t got this” to him and he later falls asleep after drinking warm milk, causing the quads to panic, although they lie to their parents that everything is fine, whom in turn lie to the children as well because Tom accidentally destroyed one of JT’s awards in his condo. When Mae and her friends arrive, the quads attempt to keep their friends from figuring out that JT is asleep, but it doesn’t go as planned when Sharon Dee and her crew from the TV network appear, and Dicky mistakenly tells Sharon that JT is quitting show business. In a last-ditch effort to save his career from being ruined, the quads try to get JT to save the barbecue by getting chips to go with the dip, which he does, saving his career. He then leaves just as Tom and Anne get back from the condo.

Nicky, Dicky, and Dawn want to get an invite to the cool student stairs; however, just the chance is put in jeopardy when Ricky dresses in an uncool manner. Later, while Ricky is asleep, Nicky, Dicky, and Dawn take away all of his uncool belongings, and Dicky then hides them. However, Ricky finds them in the freezer the following morning when Dicky lets it slip out that he hid them in there because he thought it would make them cooler. Later at school, Nicky, Dicky, Dawn, and later Mae try to create a hall wall in front of Ricky so the cool stair students don't see him. Nicky, Dicky, and Dawn then take all of the uncool articles of clothing off Ricky and put them on themselves. The quads then get into an argument, with Ricky pretending to be Nicky, Dicky, and Dawn and mocking them, and Nicky, Dicky, and Dawn pretending to be Ricky and mocking him. However, things take an even worse turn when Moses sees this and gives Nicky, Dicky, and Dawn uncool nicknames—Suspender Girl, Visor Boy, and Briefcase Man—and Ricky is then invited to be on the stairs with the other cool students and receives the nickname R-Man. Ricky eventually works his way to the top of the stairs, but Nicky, Dicky, and Dawn start coming up with a plan to get revenge. The next day at school, Nicky, Dicky, and Dawn all dress cool and start releasing some of Ricky's secrets; however, it takes mentioning that he sleep rhymes for the cool students to question Ricky's coolness. Ricky tries to cover it up by saying they're sleep raps instead and is forced into rapping, but fails and the other students laugh at him. Nicky, Dicky, and Dawn then feel bad for him and climb to the top of the stairs to rap alongside him. The rap is a success, but the quads then fall down the stairs and are consequently kicked off the stairs.

Dawn catches her brothers spying on their new neighbors moving in, though she's not aware that they're new neighbors and mentions that the FBI made it very clear they weren't to spy on their previous neighbors. When she's made aware that they're new neighbors, she brings up how she and her brothers can finally gain access to the tree house at that house. They discover that the new neighbors have a child named Syd and begin plotting on how to use her for their own needs. The next day at school, they make an attempt at introducing themselves to Syd, but she's not interested and leaves. It's later discovered at Syd's house that Syd and her family were told to stay away from the Harper family due to the quads' bad reputation, though Syd doesn't personally care about their alleged bad reputation, but because she has a bad side as well, she thinks it's best not to make friends with the quads. She also has a history at other schools, and it's the reason why her and her family moved, and if she messes up again, she'll be sent to boarding school. However, things go awry when Dawn and Syd are playing croquet while Dawn's brothers are setting up a table. Dicky forgets to lock the table's legs, causing the table to collapse; when Dawn hits the croquet ball, the table acts as a ramp and causes the ball to injure Ann, who almost catches the quads and Syd. This causes Syd to lose control and get in touch with her bad side again, and she begins swinging at and breaking windows with the croquet balls. The next day at school, the quads learn from Mae that Syd has stolen the answer book for the day's test in Mr. Williams' class; that night, Dawn tries to get the book back in the tree house, but is caught by Syd who is acting even more crazy than before. When Dawn and Syd begin fighting over red paint Syd wants to use to put in balloons and throw at cars, Dawn's brothers rush over to the tree house as they believe the paint to be blood. Syd then begins to realize the error of her ways and her and the quads truly bond for the first time. Unfortunately, the tree house then falls to the ground when a bird lands on it after Syd had mentioned earlier how her father said the tree house could only support two people, but it is still intact. However, a feather then lands on the floor and causes the walls and roof to collapse.

While unconscious, Dawn dreams that she is in Oz still fighting with Rose over who's the real Dorothy. They break into a song, after which the Wicked Witch tricks Nicky, Ricky and Dicky into giving her the Dorothy shoes. The boys go after the Wicked Witch to get the shoes back for Dawn, but the Witch captures them. She locks them up in a cage next to Dr. Colosso from The Thundermans and threatens to destroy them after turning Dr. Colosso into soup. Meanwhile, Dawn goes to find the Wizard of Oz to prove that she's the real Dorothy. Rose follows her. Once she finds the location, she discovers that there are two Wizards of Oz. The Wizards of Oz keep Dawn waiting a long time while they try to decide on what to eat. Mae then pops in and reveals to Dawn that her brothers have been captured by the Wicked Witch. Dawn gives up the role and goes to save her brothers. The wizards declare Dawn as the real Dorothy because being Dorothy means acting like her, not looking like her. Dawn wakes up and agrees to let Rose play Dorothy. Unfortunately, Rose gets hurt on stage, so the director casts Dawn as the new Dorothy.
