Vanzilla has broken down, and the kids are forced to push it, while Rita sits in the driver seat. As they push the van home (except for Lola), Rita points out that while everyone agrees that they should get a new van, their father doesn't like the idea, since the van was originally his father's, and his grandfather's van, and plans to keep it in the family by passing it down to Lincoln. When they finally get home, Rita tells them that she needs them to push the van again, and the kids decide to try to convince their dad to get a new van.
The next day, the kids try to persuade Lynn Sr. by doing favors for him that have the van involved, such as making a pancake-shaped like a van, complimenting him with van-related puns, and solving homework problems that involve car travel. The next day, Lynn Sr. awakens to the smell of a spray. Liking the smell, Lisa approaches him and tells him it's her latest experiment: a spray that replicates the smell of a brand new car. Now fully convinced, Lynn Sr. declares that the Louds are going to get a new van, much to their joy
Sometime later, Lynn Sr. arrives back home with a sleek brand new van, which he nicknames "Veronica". Amazed at the new van, the kids and Rita attempt to enter, but Lynn Sr., not wanting to get the brand new van dirty, makes his family go through inspection (which ends up taking all day). With everybody in, Lynn Sr. is prepared to take the van for a spin. However, he only proceeds to back up a few feet, and drive back forward, remarking that he doesn't want the mileage to skyrocket before kicking everyone out. When Lori and Rita ask if they ever get to drive the van, Lynn Sr. tells them they can't, since he's the only one allowed to drive the van.
The next day, Lori and Leni arrive at a new/used car lot, and a worker named Steve greets them and shows them a convertible that Lori and Leni are interested in. Lori points out that they need to take the car out for a test drive. This involves buying lunch at the Burpin' Burger, and going shopping at the mall, all while Lori and Leni manipulate Steve into letting them do this.
Back at the Loud House, it becomes apparent that Lynn Sr. has become incredibly attached to the new van, as he and the vehicle wear matching beads and hangs out at the Royal Woods Mini Van Society, where its members are minivan owners who also refuse to let their families in their vans. The rest of the family is upset at how their father is too attached to the van and theorize that getting Vanzilla back will fix everything. They try to convince Lynn Sr. into getting Vanzilla back by giving him a pizza slice shaped like Vanzilla, Rita carpooling with one of her co-workers to make him jealous, and Lana stealing Veronica's tires. However, all three tactics fail and Lynn Sr. shames his family for wanting him and Veronica split up just so they can have Vanzilla back.
At the Mini Van Society, as Lynn Sr. tells his fellow members how his family tried to split up him with the van, they witness a van owner buying lunch for his large family. The members realize that they miss their old vans since their families made some memorable moments in them. When the members go get their old vans back, Lynn Sr. realizes what he has become. He arrives back to the house to apologize to his family and asks them if they want to get Vanzilla back, which the Louds happily agree to. They arrive at the car lot to return the van, but they can't get Vanzilla back due to it being shipped to the junkyard. At that moment, Lori, Leni, and Steve, arriving back after a fun day, decide to use their car to go to the junkyard.
At the junkyard, the Louds frantically search for Vanzilla. After some searching, Lincoln manages to find it. However, a worker is prepared to crush the van in the car compactor. Lana quickly takes her slingshot, and flings one of the beads from Lynn Sr.'s beaded vest, and manages to stop the crusher before the press touches down on the van. Lynn Sr. asks the worker to buy back Vanzilla.
In the end, the rest of the Louds are happy that Lynn Sr. sacrificed Veronica to get Vanzilla back, even if they're forced back into pushing it to make it move again.
