Plot
Sue Ellen, who goes by her middle name "Tanya", is a seventeen-year-old Black girl from Los Angeles. She lives her with single mother Joan who works as a corporate executive, her stoner skateboarding riding brother Kenny, her horror movie, true crime, and video game addicted sister Melissa, and her younger geeky brother Zack, who likes to study birds, especially crows, in the San Fernando Valley area. Tanya who just graduated High School and plans to go to Howard University, is preparing for a trip to Spain, with her friends, however Tanya's mother has to go on a business retreat in Thailand, meaning she cannot go on her trip, and must watch her siblings. When Joan realizes that her children are not responsible enough to be on their own, she hires an alcoholic, heavily Christian, and pistol wielding, spinster, white babysitter, Ms. Sturak.
Although Ms. Sturak puts on a front and is polite before Joan leaves for her trip, when Ms. Sturak is left alone with the children, she is very abusive, by throwing away Kenny's cigarettes, vape pens, and marijuana; destroying Melissa's video games and movies, putting Zack in a harness as he keeps leaving the house to go birdwatching, and throwing away Tanya's clothes and makeup, and saying that she looks too promiscuous, and showing her pictures on the internet of people with STI's. Tanya and her siblings are fed up with Ms. Sturak, and decide to secretly throw a house party, lying to Ms. Sturak that they are inviting their classmates over for Bible study, which Ms. Sturak allows. Ms. Sturak who was asleep in her room, is awakened by the loud noise of the party, and decides to go downstairs to secretly investigate, suffers a heart attack due to the commotion and rowdiness.
The next morning, Tanya goes to check on Ms. Sturak, only to find that she is deceased. Not wanting to get into trouble by their mother, and the police, she and her siblings, originally decide to hide Ms. Sturak in a deep freezer in their garage. However, Ms. Sturak is too heavy, and her corpse keeps falling out of the freezer. Tanya and her siblings then decide to dispose of her body, by staging a death scene, putting her dead body in her car, and ramming her car into the river, hoping that people would assume she was drunk and drove into the water. Unfortunately, they forgot to get the cash their mother left for them out of Ms. Sturak's purse, so without any money for food, Tanya and Kenny spin a bottle to decide who has to get a job, which Tanya loses.
Tanya gets a job as a ride share driver, which does not pay well, and she barely makes enough to feed her siblings. However, she ends up picking up a handsome architect student named Bryan, who is on his way to his coworker's wedding. Tanya immediately is smitten with Bryan and is attracted to him, and Bryan feels the same way, and they have perfect chemistry and exchange numbers.
Tanya quits her ride share job as the pay is not suitable enough. However, her sister Melissa arranges a job for Tanya, at a fashion company, in which the pay is very well, and Tanya coincidentally plans to study fashion in school. However, Tanya must lie that she's a much older successful businesswoman, with Melissa (by fabricating her resume, references and records), and Kenny and Zack going along with her lie.
Tanya interviews for the job and immediately connects with the vice president of the company Rose, who hires Tanya to be her assistant. However, she clashes with her coworker Caroline (who coincidentally is Bryan's sister), who applied for the position Tanya is in, but was rejected. Tanya is successful at her job at the company, while Kenny becomes more responsible at the home, learning how to cook, and taking care of Melissa and Zack. Tanya also becomes very involved with Bryan, and he becomes her Boyfriend. While on a date with Bryan, Tanya notices that Rose fiancé Gus, is with another woman. Gus tells Tanya not to tell Rose. Tanya finds out that her siblings were secretly using her company credit card, to buy material things around the house, in which Tanya starts to feel scared she will get into trouble for this. However, to make it up, Kenny, Melissa, and Zack, throw Tanya a Spain themed party, since she could not go to the trip with her friends.
Rose informs Tanya, that the company is at risk of closing, unless they come up with a fashion presentation that prospective buyers and companies will agree with. Tanya offers to Rose that she will come up with the presentation, and host it at her house, in which Rose allows her to. While Tanya is busy with the presentation; back at home, Kenny while being distracted by hanging out with his friend, Melissa secretly eats a marijuana brownie, causing her to become extremely high and she injures herself at the house by falling off a skateboard ramp in their backyard. Still being occupied by preparing her work presentation, Tanya accidentally misses Bryan's graduation from architect school, which she promised to attend, in which Bryan decides to breakup with Tanya over this. . On the night of the presentation, Kenny, Melissa and Zack help prepare food for the guests, and Tanya has her friends (who are back from the Spain trip) model clothes to the buyers and shareholders in attendance. The presentation goes well, until Joan (who is back from her trip early) walks across the runway confused, and yells and curses out Tanya. The shareholders in attendance think this is a stunt and a skit and are entertained by this.
Tanya admits the truth to Rose, which Rose does not care and allows Tanya to keep her job at the company, while she is going to school as well. Tanya makes amends with her coworker Caroline, becoming friends with her. Bryan who was at the presentation as well, reconciles with Tanya, and they kiss. Joan asks where Ms. Sturak is. The children admit to Joan what they did to Ms. Sturak, in which Joan doesn't blame what her children did to Ms. Sturak, and agree to keep their secret.
Later, Rose is approached by Kenny's best friend Rock, who is attracted to her and asks her out, which Rose agrees to.
