To raise money to replace her family’s broken tablet, Harley rents out the family’s couch to a foreign exchange student. Meanwhile lewie and beast start an illegal animal fight ring with Daphne working for them as a bouncer and advertisement worker.
When the Diaz kids break their shared tablet, their parents refuse to buy them another one. So, Harley convinces her siblings to help them in a scheme where they would secretly rent their house in order to make money to buy the tablet. It shouldn't be that hard to sneak in another kid past their parents since they already have a large family of nine.
They are lucky to find a customer, Bai Hsu - a Chinese exchange student. He doesn't speak English; so they have to use a translator app to communicate. First, they force Bai Hsu to stay outside in the dark until their parents go to sleep. They then bring Bai Hsu inside to sleep on the couch. When he calls Georgie a kind girl, Georgie develops a crush on him. Since Rachel has been trying to get in touch with her boyfriend Cuff without luck, he posts pictures with Bai Hsu, hoping to make Cuff jealous.
During breakfast, Harley has to make sure that their parents don't notice Bai Hsu. So, Harley sabotages Suzy's coffee maker causing it to malfunction so bad that Suzy starts crying. The next night, Harley overworks her siblings to make sure nothing goes wrong. But things get complicated when their dad decides to sleep on the coach, forcing the kids to hide Bai outside. Ethan calls out her out for being too pushy. So, Harley takes Bai to Tom's Bait & Bite store to sleep in a tent there. Ethan finds Harley trapped in the tent, struggling to get out. He makes up with Harley and admits that even though Harley is pushy, it's good pushy because she makes them do things to help the entire family. He then unwraps Harley from the tent only to find that Bai Hsu is already asleep in a raft.
Early the following day, the kids rush in to look for Bai Hsu but he's missing and the raft has been sold and thrown in the water. Georgie jumps into the ocean to look for him. Tom tells Harley and Ethan that he found the exchange student and helped him move out. He tells them that he didn't let Bai pay for the stay. He had assumed that Bai was there as part of Rachel's idea to make Cuff jealous. Rachel later realizes that Cuff wasn't responding to her texts because he got arrested for painting graffiti where he tagged her on a porta-potty.
Harley gets away with it. Even though Harley complains about being the middle kid, she realizes that it also makes it easier to get away with stuff.
While the older kids are hiding an exchange student, Daphne, Lewie and Beast are charging other kids in the neighborhood money to watch frogs wrestling. When Bethany and other parents go to see the wrestling frogs, they realize that it's not actually wrestling; they were mating.
