The episode begins with a scene at the Springfield Botanical Gardens, where Lisa Simpson is excitedly showcasing her new plant, a rare species called the "Giant Carnivorous Plant." She is eager to impress her classmates and hopes to win a science fair with it. However, her enthusiasm is met with skepticism from her peers, who doubt the plant's potential.

Meanwhile, in a different part of Springfield, Homer Simpson is at work at the Springfield Nuclear Power Plant. He is approached by his boss, Mr. Burns, who is intrigued by the idea of genetically modifying plants to create a new strain that could produce more food. Burns sees this as a way to increase profits and orders Homer to oversee the project. Homer, initially hesitant, is swayed by the prospect of a bonus and agrees to take on the task.

As Homer begins his work on the project, he becomes increasingly obsessed with the idea of creating the perfect plant. He spends long hours at the lab, neglecting his family and friends. Marge, concerned about his well-being, tries to intervene, but Homer brushes her off, believing he is on the verge of a breakthrough. His obsession leads him to experiment on himself, using a serum derived from the plants he is working with.

Homer's self-experimentation results in him growing to an enormous size, much to the shock of his family and the townspeople. Initially, he enjoys the attention and newfound abilities that come with his size, such as being able to reach high places and scare off bullies. However, as he continues to grow, he becomes increasingly isolated and struggles to fit into his old life. His size causes chaos in Springfield, leading to property damage and public panic.

Lisa, witnessing her father's transformation, feels a mix of concern and responsibility. She believes that her plant may have contributed to his condition and decides to take action. Lisa researches ways to reverse the effects of the serum and discovers that the only way to shrink Homer back to his normal size is to use a special antidote made from the same rare plant she had brought to the science fair.

In a climactic moment, Lisa confronts Homer, who is now a giant and causing havoc in the town. She pleads with him to take the antidote, but Homer is resistant, feeling that his new size gives him power and respect. Lisa, determined to save her father, devises a plan to lure him to the Botanical Gardens, where she can administer the antidote.

The plan involves creating a distraction using the Giant Carnivorous Plant, which has grown significantly since Lisa first introduced it. She sets up a scenario where the plant appears to be attacking, drawing Homer's attention. As he approaches, Lisa seizes the opportunity to inject him with the antidote. The process is tense, with Homer initially resisting, but ultimately, he realizes the importance of returning to his normal self for the sake of his family.

As the antidote takes effect, Homer begins to shrink back down to his original size. The townspeople, who had been fearful of him, start to cheer as he returns to normal. Homer, now back to his usual self, expresses gratitude to Lisa for saving him and acknowledges the importance of family over his obsession with power and size.

The episode concludes with a light-hearted moment as the family gathers together, reflecting on the chaos that ensued. Homer promises to be more present in their lives, and Lisa, proud of her scientific achievements, is celebrated for her role in saving her father. The final scene shows the Giant Carnivorous Plant, now a part of the Botanical Gardens, thriving as a reminder of the adventure they all experienced.

Feeling cornered, Homer experiences a moment of introspection. He realizes that while the plant has brought him joy, it has also caused chaos and disruption in his life and the lives of those around him. This internal conflict is visually represented as he looks at the plant, which looms large and imposing in his backyard, casting a shadow over his family and home.
