Diary of a Wimpy Kid: The Long Haul

The Heffley family gathers for dinner at Corny's, where Susan reveals the exciting news that they will embark on a road trip to celebrate Meemaw's 90th birthday in Indianapolis. This announcement is met with displeasure from Rodrick and Greg, who were hoping for something more fun and less family-oriented.

During the gathering, Greg faces a humiliating situation by getting stuck in a ball pit filled with diapers while attempting to rescue his brother Manny. This chaotic incident leads to Greg becoming infamous online as the character dubbed 'Diaper Hands'.

In an effort to bond as a family away from technology, Susan confiscates everyone's phones, declaring the trip a tech-free experience. However, Greg and Rodrick find this declaration a challenge as they plan to escape by secretly retrieving their phones during the trip.

At the motel, Greg sneaks his phone from Susan and teams up with Rodrick to plot an escape to attend the Player Expo. They are determined to eliminate the embarrassment caused by the viral 'Diaper Hands' meme.

While attempting to reach the Expo, Greg and Rodrick stumble upon two mischievous brothers known as the 'Beardos'. Their reputation stems from their father's impressive facial hair, and they pose a threat to Greg's plans.

Greg unintentionally offends Mr. Beardo by mistakenly calling him a 'Fat Beardo,' igniting a vendetta against the Heffley family. This confrontation escalates as Mr. Beardo vows to take revenge on Greg for the insult.

Manny's luck takes a turn for the better when he returns home from a fair with an unexpected piglet companion. However, chaos ensues as Mr. Beardo intensifies his pursuit of Greg, leading to near disaster for the family.

In a moment of mercy, the Heffleys donate the piglet to a local petting zoo, much to Manny's disappointment. This small gesture of kindness creates a momentary respite from the family’s escalating troubles with the Beardos.

Back at the hotel, Greg and Rodrick devise a plan to surprise their parents with a gift for Meemaw. However, their escape to the Player Expo compromises their good intentions as they leap into the adventure.

Greg unexpectedly faces off against Mac Digby, a tough competitor in a gaming contest, leading to a disastrous situation when Mac’s screen crashes due to Greg's misguided attempts to impress. The incident leads to the reveal of Greg's embarrassing 'Diaper Hands' persona.

Overwhelmed by Susan's controlling nature and the challenges of the trip, Greg confronts her about her strict rules regarding technology. This leads Susan to reconsider her approach, hinting at a potential shift in their family dynamics.

As the Heffleys continue their journey, a runaway tarp takes over their motorboat, causing their belongings to scatter everywhere. Amid the chaos, the Beardos capitalize on the disarray to reclaim stolen items from the Heffleys.

Stuck in a significant traffic jam, Frank decides to take an alternative route that leads them to the Beardos' motel. This bold move results in the successful retrieval of their scattered belongings as they confront the mischievous brothers.

As they near the conclusion of their chaotic journey, Greg unwittingly finds himself adrift in a boat that has drifted from their car. A kind tow truck driver helps guide them back to the petting zoo to reclaim Manny's piglet.

Following this wild adventure, Frank is given time off work to spend with his family, while Rodrick receives funds for van repairs. In a surprising twist, Susan drops news of flying to their next destination, leaving Greg excited for upcoming trips.

In a humorous mid-credits scene, Greg snaps selfies with two girls who recognize him as 'Diaper Hands.' Their laughter at his misfortune brings a light-hearted end to his chaotic adventures.
