Plot By Wiki:
When a busload of tourists stops at the Great Pyramid of Giza in Egypt, a boy named Justin accidentally falls onto it to discover that it has been stolen and replaced by an inflatable rubber duplicate. News of the theft shocks and puzzles the world.
In the middle of a suburban neighborhood sits a black house with a dead lawn. Unbeknownst to the neighbors, hidden deep beneath this home is the vast secret hideout of the supervillain Gru (Steve Carell) and his army of naughty genetically-altered Corn Pops called minions. When he learns of the Pyramid theft, his pride is badly wounded and he resolves to pull the biggest heist in world history: stealing the Moon. Gru tries to get a loan from the local Bank of Evil (formerly Lehman Brothers), where he meets Vector (Jason Segel), and finds out that it was Vector who stole the pyramid. Mr. Perkins (Will Arnett), the bank president, refuses to give Gru a loan until he obtains the shrink ray necessary for the plan. As Gru leaves the bank, he shoots Vector in the head with his freeze ray while he is busy reloading his piranha launcher.
Gru and his minions steal the shrink ray from a secret lab in East Asia, but Vector promptly steals it from him as revenge for freezing his head; Gru makes several attempts to get it back, but cannot get inside Vector’s lair. After seeing three orphaned girls named Margo (Miranda Cosgrove), Edith (Dana Gaier), and Agnes (Elsie Fisher) get into Vector’s lair, Gru adopts them to steal back the shrink ray. Vector has placed a large cookie order, and Gru has his assistant, Doctor Nefario (Russell Brand), build several cookie-shaped robots to slip into the boxes. The cookie robots are designed to help steal the shrink ray from Vector’s vault. The heist nearly fails when the robots seal Gru inside the vault, but he and his minions eventually escape through the main entrance.
Gru begins to bond with the three girls at local amusement park, “Funland.” He fine-tunes his plan and presents it to Mr. Perkins, who surprises him by still refusing to give him the loan. Perkins then tells Vector (revealed to be his son Victor, who named himself after the math term) that Gru has the shrink ray. Though Gru is ready to abandon his plan due to lack of funds, the girls and the minions take up a collection to keep it going. Nefario begins to see the girls as a distraction and has them sent back to the orphanage, breaking Gru’s heart.
The heist falls on the same day that the girls are to participate in a ballet recital. Gru shrinks the Moon, pockets it, and rushes back to Earth, but he misses the recital. He finds a note from Vector, who has kidnapped the girls, telling him to bring the moon. After forcing Gru to hand over the moon, Vector does not return the girls, but instead takes them into space aboard his escape pod. Gru gives chase as the effects of the shrink ray wear off (which Dr. Nefario calls the “Nefario principle,” the greater the mass of an object before shrinking, the faster the effect wears off), causing the Moon to grow and smash open the cell holding the girls. Gru rescues them with the help of his minions, while the (rapidly-expanding) Moon wrecks Vector’s controls so that his pod rockets the moon back into orbit.
Gru and the girls settle down to live a happy life as a family, while Vector is stranded on the Moon. The girls give a special recital for the minions, Gru, and his mother (Julie Andrews), who finally tells him she is proud of him. The music changes and everyone present rushes onstage to dance.
