Diary of a Wimpy Kid: Rodrick Rules

As Greg's parents get ready for a weekend away, taking Manny along, the stage is set for potential mischief at home. Rodrick, Greg's older brother, sees this as the perfect opportunity to throw a party without supervision, setting off a series of chaotic events.

Rodrick begins his party, coaxing Greg into helping him with the preparations. However, while Rodrick enjoys the festivities, Greg ends up doing all the work, making him realize the unfairness of the situation as he takes on more responsibilities.

In a clever move, Greg loosens the doorknob to create leverage against Rodrick. He captures evidence of the party on his camera and uses it as blackmail to make Rodrick comply with his demands, showcasing his resourcefulness.

Just as they settle into the aftermath of the party, Greg receives an alarming call from his mother. She informs them that Manny has fallen ill, causing their parents to rush back home immediately, throwing the brothers into a panic.

With their parents on the way, Greg and Rodrick frantically attempt to clean up the mess from the party. They usher out remaining guests and try to switch Rodrick's bedroom door with the bathroom door to hide evidence of the chaos, but their plan fails when the door doesn’t lock properly.

In the aftermath of their cleaning dilemma, Rodrick shares his infamous 'Rodrick Rules' with Greg, teaching him the art of doing minimal work. As Greg's frustration grows, he contemplates how to get back at Rodrick for his earlier manipulations.

As Greg experiments with drumming, Rodrick encourages him to join his band, Löded Diper. This unexpected opportunity allows Greg to delve into a musical journey, despite the band's unconventional lineup with an unexpected thirty-year-old member.

Greg, skeptical about his friend Rowley's magic act for the upcoming talent show, agrees to help despite reservations. This collaboration leads to humorous mishaps even as Frank grows suspicious of their secretive behavior.

During a chaotic visit to the nursing home where their Grandpa lives, Rodrick's distribution of 'Mom Bucks' leads to a series of mishaps for Greg. One such blunder results in Greg accidentally entering the women's restroom, escalating into a wild chase.

With a looming deadline for a life science project, Rowley reminds Greg to ask Rodrick for help. Rodrick agrees to assist in exchange for Mom Bucks, but his support is disappointingly minimal, resulting in a lackluster project.

Greg confronts Rodrick about the poorly executed project, leading to a heated exchange. As Greg demands compensation in Mom Bucks, Susan, their mother, overhears the conversation, uncovering their devious plan and grounding both boys.

In an unexpected turn of events, Rowley sends out incriminating photos, leading to wild rumors about Greg's supposed talents. This newfound notoriety complicates Greg's participation in the talent show and his relationship with Rowley.

As the talent show approaches, Greg finds himself torn between performing with Rowley or joining Löded Diper as the new drummer. The decision weighs heavily on him, magnifying the complexities of friendship and family dynamics.

Just before the performance, Rodrick's disheartened expression prompts Greg to reflect on their sibling relationship. In a heartfelt moment, he expresses his desire for Rodrick's approval, leading to a deeper understanding between the two brothers.

With renewed confidence, Greg reinstates Rodrick as the drummer for Löded Diper despite the grounding. Their parents take pride in their efforts, while their bond as brothers solidifies, demonstrating that family can overcome any chaos in their lives.
