| Sinopsys: | When the Heffley family attends a pool party at the local pool to start off the summer, Greg (Zachary Gordon) is found playing Twisted Wizard 2 on his PSP. The family meets a former trouble-making friend of Rodrick who is now a model student after attending a military school known as Spag Union. Frank (Steve Zahn) wants Greg to do something outdoor sy by swimming. Manny (Connor & Owen Fielding) calls Greg over to the baby pool. He laughs and says he is peeing. After Greg watches other toddlers urinating in the pool, to his horror, the show begins with Greg speaking to the audience about summer and that he and Frank have nothing in common. But at least if he stays a step ahead, Greg claims that he has a shot at a great summer.
On the last day of school, when last period almost ends, Greg attempts to get his crush Holly Hills (Peyton List) to put her phone number in his yearbook in addition to signing it. However, she is forced to leave with Patty (Laine MacNeil) before she can write the last two numbers. The school hallway is a zoo. While Greg finally makes it out, Greg attempts to ask Holly to finish, but she sees his brother before he can finish his request. Meanwhile, Rodrick (Devon Bostick), who is advertising his band at Greg's school, takes Greg's yearbook and realizes that the picture is of Greg as a little kid because Greg was sick on picture day. A car comes by, and Holly is forced to leave for a ride. Greg tries to speak, but Rodrick shoves him. Soon, he falls in love with Holly's older sister, Heather Hills (Melissa Roxburgh).
Because the phone number only is missing the last two numbers, Greg tries to call every possible two numbers. Unfortunately for him, he never receives an answer from Holly. Later, Susan (Rachael Harris) makes a book club called "Reading Is Fun." Sometime later, Greg's best friend, Rowley Jefferson (Robert Capron) takes Greg to the local country club, which Greg takes a liking to instantly due to the seemingly free food, the sparsely populated pool, and the fact that Holly teaches tennis there. While at the club, he arranges a tennis match the next day despite the fact that he and Rowley have never played tennis. When Greg returns home, he finds his father has offered to sign him up for an internship at his job, but Greg makes up a hasty lie about having a job at the country club to get out of it and to go to the country club every day. The next day at the tennis match, it becomes painfully obvious that Greg and Rowley have never played tennis, and Holly teaches Greg personally.
At a party at Warren's, Greg's dad decides to get a dog for the family and to sign Greg up in the Wilderness Explorers (a parody of the Boy Scouts of America) to teach him responsibility after hearing it worked with Warren's sons. At the same party, Rodrick finds out that Greg does not have a job, and he blackmails Greg into sneaking him in to the country club to see Heather, though his attempt to talk to her ends horribly. Later that day, Frank gets the dog. Greg wants to name the dog Shredder or Ripjaw, but the names are too violent. Then Manny names the dog "Sweetie", who proves to be a handful after being walked through the town.
Rowley invites Greg on a family trip to their beach house near the Boardwalk. Just before Greg leaves, his parents give him a ladybug cell phone, which only allows him to call home and 911. Greg sees that the house that they are staying at is far away from the boardwalk. The Jeffersons play a game of "I Love You Because." When Greg has to compliment Mr. Jefferson (Alf Humphreys), he has no idea what to say. (He might have eventually answered, but whatever else he had to say is skipped). When they visit the amusement park, Greg convinces Rowley to go on the Cranium Shaker despite Rowley's conservative parents telling them to not go on scary rides and to meet them back in one hour. Rowley feels nervous since he had promised his parents. They get on the ride, and it is not a pretty sight. At the end of the ride, Rowley's parents find out, and they tell Rowley that they were searching everywhere and they were about to call the police to report him missing. Rowley feels guilty when they tell him that they are disappointed in him. At home during bedtime, he hates the sleeping situation, and Greg attempts to email his mother asking her to help him leave while Mr. Jefferson uses the restroom, but he accidentally emails everyone on Mr. Jefferson's contact list. Panicking, Greg tries to escape by calling his parents using his ladybug, but when he pushes the house button the phone tells him that it cannot take his call. He tinkers with the phone, but he then accidentally presses the 911 button. The Police arrive and attack Mr. Jefferson for having a knife in his hand. Greg is then sent home early, and Frank tells him that Rowley is a bad influence because Greg always gets into trouble around him.
Later, when Greg asks Rowley to take him again into the Country Club, Rowley lies and states he is not going there. Still, Greg sneaks in, pretending to be a member of the Jefferson family. After falling from the high dive naked, he runs into Holly and her sister and manages to get Löded Diper a gig at Heather's 16th birthday party. He meets Rowley, who tells him he had lied to protect Greg's feelings because his parents didn't want to invite Greg. He and Greg make up, however Rowley's father becomes infuriated that Greg has built up a massive smoothie bill and tells Frank, who then finds out Greg does not have a job and is forced to pay himself. Much to Greg's horror, he intercepts a promotional package from Spag Union directed to his father, and Greg fears that he is going to be sent there.
Rodrick says his last chance is the "Wilderness Weekend" where he can attempt to impress his Dad while out on a camping trip. However, their troop proves to be weak compared to Troop 42, led by Warren (Phil Hayes), who pitch their tents where Greg's troop was about to stay, forcing them to put their tents next to the bathroom. Greg and his friends overhear Stan and his sons mocking Greg's father and plan to set up a trap for revenge involving a nest of ants. However, Warren's expensive tent gets destroyed, and Greg discovers that Troop 42 has not been camping but living off of excessive conveniences. When Greg steps up and takes the blame, Frank is impressed and finds out about Troop 42's electronic convenience. Frank angrily confronts Warren as a phony, and Warren falls into the trap that Greg, Rowley, Fregley (Grayson Russell), and Chirag (Karan Brar) made. As a result, Warren is chased by bees and a bear. Frank later takes Greg to a hotel and reveals he never liked camping. He tells Greg that he will not send him to Spag Union and that he is proud of him.
At Heather Hills' Sweet 16th birthday party, Löded Diper performs a rock version of Justin Bieber's "Baby" during an attempt to win over Heather. However, they end up ruining the party and humiliating her in the process. Greg apologizes to Holly, however she states she is happy as she felt that her sister deserved it. Then, Holly holds Greg's hand, implying that she likes him. The film ends with Greg, Rowley, and Holly swimming at the community pool, eating hotdogs, and enjoying the rest of their summer. |
