Invisible Sister is the comedy adventure story of Cleo (Rowan Blanchard), a tween girl whose science project goes terribly wrong, making her popular older sister, Molly (Paris Berelc), suddenly invisible!
Cleo Eastman (Rowan Blanchard) is a teenage girl living in the shadow of her older sister, Molly (Paris Berelc), whose popularity gets her recognized by everyone at school. Although Cleo is hardly noticed compared to her sister, she is an excellent student, but is introverted and somewhat sarcastic and cynical.
Cleo's science teacher, Mr. Perkins (Alex Désert), sees her potential in science and decides she needs a challenge for her class project; she is to determine a mystery substance and transform it into its crystal state. As she works on the experiment at home, while Molly hosts a dinner for her lacrosse team, a moth flies by and distracts Cleo, causing her to accidentally spill unknown chemicals into her solution. The steam produced ends up turning the moth invisible, leading Cleo to chase it around the house, full of guests, before it gets away.
Later, while Molly is preparing for bed, the moth returns, attracted to the light from the bathroom. The moth falls into a cup of water containing an antacid Molly is about to drink, and she unknowingly consumes the moth which renders her invisible.
The next morning, Molly is horrified when she cannot see herself and discovers the reason from Cleo. She must attend school to participate in the season opener for her lacrosse team, which college scouts will be watching. As it is Halloween, she decides to wear her costume to mask her invisibility, but when the costume also turns invisible, Molly has Cleo wear the costume and pretend to be her at school. Cleo attends the pep circle for the lacrosse team while Molly grabs a microscope from the science classroom so Cleo can figure out how to make her visible again. In the process, Molly hears Carter (Will Meyers), a boy Cleo likes, talking with George (Karan Brar) about Cleo; she manages to secure a date for her sister by pretending to be her and asking Carter out. Things get complicated when George finds out Molly's invisibility, and her boyfriend Coug (Austin Freyberger) questions why she is constantly avoiding him. Later in the lacrosse game, Cleo has a rough start but slowly gets into the game with Molly's help, resulting in a victory for the team.
Upon observing Molly's cells under the microscope, Cleo and George conclude that her invisibility will become permanent unless they can formulate an antidote before midnight, twenty-four hours after Molly swallowed the moth, so they need to reproduce the results from Cleo's earlier experiment. The sisters go to a cemetery to catch another moth while George goes to school to set up. While in the cemetery, Molly's frustration over her invisibility mounts, leading to a heated argument with Cleo. In apologizing, Cleo admits to admiring Molly's "light" and is jealous because her not sharing in it makes her feel invisible. After Molly secures a moth for the experiment, the sisters take a trolley to school. While in transit, Molly tells Cleo she understands her feeling invisible, but she also envies Cleo's genius, as she knows her popularity is fleeting. Cleo clarifies to Molly that her "light" is about more than popularity.
When they arrive at school and meet George, they realize they need to get past the security guard. Using her invisibility, Molly manages to scare him out, allowing Cleo and George to enter and duplicate Cleo's original experiment. The solution turns out to be too complex for either Cleo or George to understand, and they need Carter, a governor's scholar, to analyze the results.
They look for him at the school's annual Halloween party "Romp the Swamp". While searching, Cleo bumps into Coug, who is doubting his relationship with Molly and needs to be shown she cares for him, despite being invisible. Eventually, Cleo finds Carter, who is upset with her mixed attitude, expecting they would be together for the party. After informing him about the situation, she takes him to a nearby barn, where her sister, Coug and George are gathered.
With time running short, Cleo, George, Carter and Coug work together to develop an antidote for Molly, narrowly making the midnight deadline. They nearly get in trouble when Mr. Perkins, in charge of the party, finds them in the barn, but Molly informs him about Cleo's experiment before drinking the antidote, risking the deadline. When she finally gets to the antidote, it fails but not because it passed midnight. Molly had taken some antacid the night before when she consumed the moth, so after Cleo adds a dose of that to the antidote, Molly becomes visible again upon drinking it.
Astonished by the results of Cleo's project, Mr. Perkins asks her to present her findings at a seminar of the New Orleans Association of Applied Scientists. Cleo gains a greater appreciation for the fine line between visible and invisible.
