The episode begins with Lindy rescuing Richard from Mr. Magoo's clutches. She manages to lock Mr. Magoo in the bird cage and tends to Richard's wounds, sincerely apologizing to him. She then turns to him for help with her TikTok, seeking a fresh start.
Lindy releases a video admitting her mistakes and rescinding her Pulitzer. Lulu is deeply touched when she arrives at the airport and sees the video and her friend waiting for her.
Les arrives and finds Mr. Magoo secured, begging Lindy for a chance to talk. He asks for her help to get back to the lab and restore her size. They hatch a plan to break into the lab, but they realize that Hilton has taken all the formula vials.
Les decides to change the plan and gets into the lab in order to synthesize a new vial. Meanwhile, Janet realizes that she can't wipe the server as Vivienne and Hilton have switched passwords. Hilton has also miniaturized several military tanks and weapons. They ask Janet to turn up the pressure valves, giving Les a chance to make a new formula before the place blows up. Richard, meanwhile, confesses his feelings for Janet before she exits the building.
Janet secures Les' entry into the lab, but not before Vivienne spots Lindy. With Lulu's help, Les completes the formula by studying the equations on his bedroom walls. However, he's uncertain about the last equation and chooses to lie, assuring everyone he's in control. On his way out, he runs into Vivienne, who has Lindy in her grasp. Les is distracted and drops the vials, which Vivienne pushes into the tight spaces between the elevators. When Lindy shocks Vivienne with an electrical charge, the latter collapses.
Lindy prepares to descend the elevator ducts to retrieve the vials. Les miniaturizes himself to accompany her, as everyone, including Vivienne, evacuates the building. By the time the place erupts into chaos, Lulu is outside, bracing for the worst. Thankfully, Les and Lindy emerge safely with the vials. They hurry out before the police arrive.
Upon returning home, Les confesses his uncertainty about the formula and volunteers to be the first test subject. Lulu sees this as an opportunity to confess her expulsion from school. They lock him in the tub and apply the formula. Thankfully, he's restored to his normal size. They quickly restore Lindy, and Lulu tends to Richard while their parents reconcile. They decide to give their marriage another chance. Lindy requests to write about her miniaturized experience, and Les embraces the idea.
The series concludes with Vivienne finding the miniaturized Nils on the street. He thought he was finally free, but unfortunately for him, he remains in his reduced state!
