Read the complete plot breakdown of Diary of a Wimpy Kid (2021), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.
In the first installment of what Greg Heffley insists on calling his “journal”—definitely not a “diary”—he sets out to share his candid thoughts and experiences as a typical middle school kid. A reluctant chronicler, Greg has reluctantly agreed to keep this journal under the pretense that it might lead him to fame and fortune, which, to his dismay, is far from his current reality. With a sigh, he shares his disdain for the “morons” he shares his school with, a sentiment that will resonate with many adolescents navigating their own school experiences.
As he scribbles on about his life, Greg dives into the notorious Cheese saga that dominates the school rumors. The chaos began when an old, moldy piece of cheese was abandoned on the basketball court, transforming into a symbol of dread—the infamous “Cheese Touch.” Anyone unfortunate enough to touch the grotesque cheese is uniquely afflicted, carrying the stinky burden until they can conveniently pass it on to the next victim. Having narrowly escaped this fate when the last possessor left for California, Greg fervently hopes the curse won’t find him.
His contemplation also includes his ever-enthusiastic best friend, Rowley Jefferson, whose pure-heartedness often complicates their friendship. Greg longs for popularity, but Rowley remains blissfully unaware, leading Greg to repeatedly explain the ins and outs of social status to his naive companion.
As Greg chronicles his life, we witness the often-volatile dynamics in the Heffley household, particularly the ongoing sibling rivalry with his older brother, Rodrick, who finds immense pleasure in tormenting him. On the other hand, Manny, the youngest Heffley, manages to escape blame for his daily mischief, relying on his cuteness to charm his way out of trouble.
Greg’s father, a firm believer in outdoor activities, disapproves of his son’s love for video games and tries to steer him towards more physically engaging pursuits. Unbeknownst to Greg, his dad has a quirky Halloween tradition of startling trick-or-treaters by hiding behind bushes and drenching them with water—a surprise that adds a layer of unexpected hilarity to their holiday.
Seeking inspiration, Greg and Rowley attempt to capitalize on the popular haunted house trend at Crossland High School by designing their own scary attraction. However, their venture nets them a meager two dollars, ultimately leading to an unforeseen turn of events on Halloween where they are ambushed by water-wielding teenagers.
Upon returning home, they find themselves drenched once again, this time thanks to Greg’s father, who mistakenly believes they are up to no good. The unpredictable twists of family life provide as much amusement as the holiday festivities.
Fast forward to school, Greg faces a jolt of reality in Geography class when Patty Farrell reminds him of his subpar knowledge of state capitals. This academic embarrassment is compounded by the pressure of auditioning for the school play based on The Wizard of Oz, where Greg is cast as a tree—much to his chagrin—while Patty secures the coveted role of Dorothy. As opening night nears, Greg’s anxiety spirals into chaos when Patty’s glasses shatter, triggering a premature end to the show, a mishap that Greg finds secretly thrilling as he contemplates revenge against Patty.
The chaos doesn’t stop there; the holiday season rolls around, bringing its own set of challenges as Greg grapples with underwhelming gifts and plots revenge against Rowley involving a Big Wheel and a football. This backfires dramatically when Rowley’s hand is broken, leading him to receive an influx of attention from girls, causing Greg immense jealousy.
Desiring a sense of authority, Greg joins the Safety Patrols at school with Rowley in tow, where they enjoy benefits like free hot chocolate. Greg’s ambitions soar as he sets out to become a cartoonist for the school newspaper, collaborating with Rowley on the comic strip Zoo-Wee Mama! However, as Greg’s creativity burgeons, so does the tension with Rowley, who claims sole ownership of their strip.
A series of comedic mishaps ensues when Greg is mistaken for Rowley while chasing after kindergartners with a worm on a stick, leading to Rowley’s temporary suspension from the Safety Patrols. Eventually, justice prevails, and Rowley is reinstated with a promotion, leaving Greg pondering the repercussions of his antics.
As the school year wraps, Greg’s aspirations to be featured in the yearbook as “Class Clown” begin to unravel when he discovers that Rowley has taken on the role of the cartoonist, keeping “Zoo-Wee Mama!” unchanged. Feeling slighted, Greg confronts Rowley, where tensions flare as they argue about credit for their comic creation. Their fight escalates when they are confronted by their Halloween bullies, culminating in an encounter with the dreaded Cheese once again.
Greg skillfully weasels his way out of consuming the dreaded cheese by pretending to be allergic, while Rowley is left holding the bag—literally. The following day, amidst the rumors of the cheese’s disappearance, Greg claims to have disposed of it, further securing his reputation as a master of manipulation.
In a surprising twist, Greg reaches a truce with Rowley, allowing himself to be recognized as the unwitting guardian of the infamous Cheese Touch. The story culminates with Greg’s yearbook distribution, only for him to discover Rowley has been crowned “Class Clown.” In a fit of frustration, Greg thrashes the yearbook into the trash—a defiant act that unknowingly grants him the very affliction he aimed to avoid: the Cheese Touch, setting the stage for more hilarity in their ongoing adventures.

Still wondering what the ending of Diary of a Wimpy Kid (2021) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.
At the end of Diary of a Wimpy Kid, Greg finds himself in a surprisingly advantageous position after taking responsibility for his friend Rowley. When Greg breaks Rowley’s arm during a reckless game, he fears losing their friendship and tries to hide the truth from their parents. Their fight worsens when Rowley’s popularity rises after a comic he submitted; Greg, feeling jealous and left out, lashes out at him. This culminates in a confrontation where they drift apart, hanging out with different groups and arguing over small things like a game.
However, a pivotal moment occurs when Rowley gets his revenge by forcing Greg to eat the infamous cheese—an old school legend that signifies social rejection—matching Greg’s earlier acts of selfishness and betrayal. In a selfless gesture and to protect his friend, Greg decides to take the blame and inherits the “cheese touch” himself. This move ironically turns Greg into the school pariah, but it also grants him the freedom to sit where he wants and avoid bullies, effectively allowing him to “fly under the radar” and live more comfortably for the rest of middle school.
In the final scenes, Greg learns that true friendship and being true to oneself matter more than popularity. He recognizes that while making mistakes is part of growing up, genuine friendship requires sacrifice and honesty. By taking responsibility for his actions and showing kindness, Greg mends his bond with Rowley, who, despite everything, accepts him back. The ending underscores a central message: that real friends are more valuable than superficial social status, and sometimes, doing the right thing means putting others before oneself. Ultimately, Greg’s journey highlights the importance of honesty, sacrifice, and staying true to who you are.
