The Louds are a busy family unit. With each one occupied with his or her commitments, they never take the time to prioritize other stuff, like excelling in school, realizing their psychological needs, ensuring their modes of transportation and maintaining the housekeeping of their own home.

Lynn Sr. is occupied with his inconsequential work as the CEO of a frozen food company. Rita is the master of her craft of leading her own book club, where she recommends books by other rich authors. Lori is more invested in golfing rather than in prioritizing her studies. Leni is keeping up with fashion trends rather than her unfashionable class performance. Luna goes with flow of her expensive guitar and her expensive attendances to rock concerts. Luan is busy fanning over profound theater experiences. Lynn Jr. is traveling from town to town through her prestigious baseball team. Lincoln has a lot of friends but no solid best friend. (Clyde is just paid to be his best friend.) Lucy is brooding in the shadows as dedication to an exclusive gothic club. Lola is an obligatory favorite within the young pageantry community. Lana is reaping the benefits of her Girl Scouts' access to wildlife. Lisa spends most of her time for inaccessible research that are governed by major Ivy League campuses. And Lily is simply spoiled.

There are constant demands for each Loud family member. And each has an employed staff to fulfill their other needs: a driver for Lynn Sr., an housekeeper for Rita, a tutor for Lori, a dummy for Leni, a roadie for Luna, a companion for Luan, an aid for Lynn Jr., a true best friend for Lincoln, a bodyguard for Lucy, an assistant for Lola, a pet watcher for Lana, a colleague for Lisa and a babysitter for Lily. And they all meet their demands.

However, Lori's tutor Hugh, an English stud muffin, leaves for England but he refers another tutor who can take his place. He is a British-Spanish professional, whose name is claimed to be Robert Centi. "Robert" visits the Louds' place where he is interviewed by the posh Rita, who phones in with a British accent. He demonstrates how effectively he can tutor Lori…by throwing in romantic lines to lure her to study. His lines go like "I feel your pulse. It means that your blood is flowing through the veins, to my heart and out to my aortas". Lori falls in love with him. And he is hired.

Leni's human dress form suddenly contracts tetanus with a rusted needle, forcing Rita to drop her. So, Robert refers another dummy for Leni, an expert fashion designer named Lottie Cassius. On the day of her interview, Lottie bonds well with Leni. Rita finds her as the perfect dress form for Leni, hiring her on the spot.

Suddenly, Luna's roadie trips on wire and hits head on a hard metal amplifier, causing him a coma. Thus, Rita calls out for applications to be Luna's roadie, strictly rock-and-roll fans. However, Lottie tells Rita to call her cousin Cool Charlie, a diminutive roadie with a lot of passion for rock music…and chicks. When the Loud family mother calls him in, he is rather obnoxious. Yet, Luna gets sold on his energy, making him get hired.

Meanwhile, Luan's companion is incredulously unaware that Luan holds large-scale pranks during April 1st. So, she quits immediately. Not wanting to spoil her daughter, Rita opens up the vacant position. That is when Cool Charlie recommends a friend named Mary Grande, a theater and comedy enthusiasts who loves volunteering for the local hospital. When Rita brings her for a fact check, Mary throws in helpful trivia to Luan and even exchanges quips with her. This helps her win Rita's favor into hiring her. In addition to that, Mary establishes a "belt of trust" to Rita whenever she needs help in employing more staff for her spoiled household.

When Lynn Jr.'s nurse is suspected of doping her, Rita fires her and hires expert sports physician Arthur Santis.

When Lincoln's fake best friend is accused of stealing his prized Ace Savvy comics, Rita fires him and brings in comic enthusiasts Roseanne Day.

When Lucy's bodyguard unintentionally loses Lucy to the girl's section of a department during a large sale, Rita fires him and hires an unlikely yet loyal busybody named Chas Jolie, as a "way" to open opportunities to employ people with disabilities.

When Lola's assistant accidentally dyes her hair green, Rita fires her and hires parlor specialist and experienced beauty pageant makeup artist Cassie Friday.

When Lana's pet watcher inadvertently feeds the exotic rodents with laxative-laced bacon, Rita fires him and hires beaked nature enthusiast Brian "Serge" Fellows.

When Lisa's colleague is discovered to be using plagiarized manuscripts to aid Lisa's research, Rita (you guessed it) fires her and hires Spanish mutation physicist Professor Carlos E. Javier.

When Lily's babysitter is caught sleeping on the job when Lily is about to walk to the oven, Rita fires her and hires a Korean-speaking welfare worker named Cho Chang; she hires for the merits of being adopted to a Chinese-American family and being a "dreamer".

When Lynn Sr.'s driver is suspected of "crossing the line" by using the Louds' car for explicit reasons, Rita boots him off and hires a more caring driver in Puerto Rican immigrant Ernesto de la Cruz, who knows all the ways and lines around Michigan.

And finally, when Rita's housemaid/assistant is sought to have an unchecked history of a critical illness, Rita boots her off and hires a motherly housemaid and expert cook Carmelita Rosales, who claims to be a distant relative of Lin-Manuel Miranda and Danny Trejo.

With that, new occupants are employed to serve in the Loud House, much to their delight. One time when the Loud family takes a camping trip to Montana, the new hires to Casa de Loud suddenly converge in the Loud House to lavish on their riches, try their various amenities, gobble on the expensive food and celebrate together in the living room over how they conned the Loud family while praised for their hospitality.

It turns out that all the new thirteen hires are actually related biologically. They are all members of the Casagrande family. Ernesto de la Cruz is Abuelo Hector with a singing voice. Carmelita Rosales is Abuela Rosa in formal uniform. Robert Centi is Bobby Santiago with a fake British accent. Lottie Cassius is Carlota. Cool Charlie is Carl pretending to be a short man. Mary Grande is Maria pretending to like Luan's acting fondness. Arthur Santis is Arturo forced into action, much to Maria's disdain. Roseanne Day is Ronnie Anne phoning in to be ghetto. Chas Jolie is CJ acting very well. Cassie Friday is Aunt Frida. Brian Fellows is Sergio in a human disguise, with Lalo as the body concealed in a trench coat. Professor Carlos E. Javier is obviously Uncle Carlos. And Cho Chang is (who else than) Sid Chang.

Hector gloats of Lynn Sr.'s acceptance on him and gives a toast to the Casagrandes over their victorious conning. With the family laughing despicably like minions with an evil plan, Hector wonders, "I wonder who we can trick next. Mwahahahaha!"

(That is actually on the mind of Ronnie Anne right now as she reports for her English class about the last movie she saw. And the last movie she saw was Bong Joon-ho's Parasite, along with Sid. Sid humorously summarized that film in the same manner above. So, Ronnie Anne goes along without questioning her best friend.) April Fools guys!
