Zachary Levi and the voices of Justin Long, Matthew Gray Gubler, Jesse McCartney, Anna Faris, Christina Applegate and Amy Poehler. The film features Alvin and the Chipmunks and their female counterparts, The Chipettes. It was directed by Betty Thomas and distributed by 20th Century Fox, with Regency Enterprises and Bagdasarian Productions. It was originally scheduled to be premiered on March 19, 2010, but it was moved up to a Christmas 2009 release instead and later a December 23, 2009 release date in the US and December 21, 2009 release date in the UK. However, it was released on December 26, 2009 in Australia.
During the Chipmunks' "Save the Music" benefit concert, sponsored by VH1, in Paris, Dave tells Alvin to take it easy, and that the concert "is not all about you", but Alvin has a difficult time listening. He then jumps on top of a scaffolding, and causes an Alvin billboard to fall. He warns Dave to look out, but it sends Dave flying across the stage, yelling "ALVIN!", into some electric devices.
After the accident, he is rushed to the hospital. Although he survives, he must stay for a few days to recover. The nurse gives him a sedative that will make him fall asleep in a minute, so he tells his boys that he's leaving his Aunt Jackie in charge of the Chipmunks until he returns. Also, he tells Alvin, Simon, Theodore that while he's away, he wants them to have a normal childhood, and that he has also made arrangements for them to go to school. When Dave goes to sleep, a woman comes to escort the Chipmunkshome, but Alvin doesn't want to leave Dave, so he runs amok. He messes with the hospital bed, causing Dave to go up and down, Theodore to crash into a trash can, and Simon to fall in the sink, but a doctor injects sedative into Alvin's rump, and he sings "Daydream Believer" until he is fast asleep. The doctor tells the woman that, for her sake, Alvin is asleep for the entire flight. Simon suggests that he inject Alvin again, just in case.
The Chipmunks land at the airport, where they meet up with Aunt Jackie, who introduces her grandson Toby, a former high school dropout. He is playing on a Nintendo DS, paying no attention to them. Toby then accidentally knocks Jackie's wheelchair down some stairs while getting the boys' luggage, and an airport luggage trolley crashes into her. She is also sent to the hospital, so Toby is left in charge.
Back at the house, they have fun eating "Cheese Balls" (Alvin also sings a slightly different version of "Stayin' Alive") and spinning in a kitchen appliance, singing "You Spin Me Right Round (Like a Record)", but they end up in a hooked pan holder. Dave calls them, and Simon and Alvin answer, but when Theodore joins them, he causes a pan to fall, and Dave wants to what's going on. Simon warns Alvin to not stress him out (so Dave can come home soon), so Alvin lies that Jackie is making them a five course meal, but when Dave finds out he cannot speak to her, he becomes suspicious, so Alvin can do nothing but hang up, causing Dave to yell "ALVIN!" and his stress monitor to beep wildly.
When attending West Eastman High School on their first day, the chipmunks are soon bullied by Ryan Edwards and his athletic friends due to their fame and high status (which attracted all of the girls). Though Alvin remained a tough target by giving Ryan and his friend Xander a wedgie, Simon received a swirlie while Theodore is taunted about his weight until his two brothers attacked them and landed themselves in the pricipal's office. The boys have fun being babysat by Toby, mainly because he is basically a big kid himself. Theodore tries to bond with Toby but Toby is always either ignoring him or being short towards him.
Meanwhile, Ian Hawke the rude selfish greedy soundtrack-editor now lives in the basement of Jett Records. But, a FedEx mail comes to the building and a package falls out. And, three singing female chipmunks, the Chipettes, Brittany, Jeanette, and Eleanor come out of it and want to be famous like the Chipmunks. So they sing Put Your Records On to make Ian adopt them. He does, telling them that the Chipmunks ran away from him and left him broken-hearted, to make the Chipettes not trust them. He lets the Chipettes stay in his apartment (in actuality, breaking into a model suite) and have their own dressing mirrors.
Meanwhile, the Chipmunks enter the school concert to win $25,000 and save the school's music program after realizing the principal was a fan. After Alvin displays some athletic prowess in dodgeball, he starts hanging out with the jocks of the school and slowly becoming distant with his brothers. This leads to random blowouts between Alvin and Simon, but the one who is most affected is Theodore who believes he is losing his brothers with them fighting all the time. The Chipmunks meet the Chipettes and fall in love, until they discover they're with Ian. The Chipettes sing Hot N Cold to get Dr. Rubin, the school principal to enter them in the contest. The Chipmunks and the Chipettes compete against each other in a Battle of the Bands. Alvin warns Brittany about what Ian did to him and his brothers, but she doesn't believe Alvin. Alvin, though reluctantly, allows Simon to be humiliated in front of everyone when one of the jocks tricks him into thinking he's now the school Litter Moniter and he ends up being thrown into the dumpster. At the concert, the Chipettes win after Simon and Theodore forfeit the competition because Alvin failed to show up (he hung out with the football team instead). Eager to get rich, Ian videotapes the Chipettes performance and posts it on YouTube, along with his phone number. Finally, Alvin shows up only to see that everyone's gone. A disappointed Brittany calls Alvin selfish and stated that she never wanted to win the way Ian was making her. When Alvin returns home, Simon and Theodore pretend they're sleeping and ignore him, forcing him to live with his guilt and failure to live up to his promises. The embarrassment is too much for Theodore to take who runs away to the zoo. When Toby and the boys find and save him from an eagle, it brings out the best in all of them and the two Chipmunks forgive Alvin and go back to "One for all, and three for one". (As Theodore put it.)
Soon, the Chipettes are hired as the opening act at a Britney Spears concert at the Staples Center. Since the concert is on the same night as the school concert, Ian decides to blow off the battle and get the Chipettes to perform at the concert. When Brittany notices that Ian plans to only make Brittany a star (by showing her a golden dress and silver ones for Jeanette and Eleanor), she rebels by saying she won't do it without her sisters. Unwilling to let anything get in his way, Ian grabs them by their tails (like he did the Chipmunks in the previous movie) and threatens to barbeque them if they didn't do what he said.
At the school, Alvin gets a phone call from Brittany, saying that she and her sisters have been locked in a cage and that she admits that he was right all along about Ian's sinister nature. Alvin races to save them on his red motorbike while Simon tells Jeanette how to open the cage on the phone. The Chipettes escape from the cage, climb out of the limo, and they jump onto Alvin's motorbike. (The Chipmunks' cousin, Digger makes a cameo during the chase) While being chased, Brittany holds onto and apoligizes to Alvin for not listening to him about Ian. Ian pursues them with an R.C. helicopter, but they leap off the motorbike and grab onto the helicopter. Jeanette than snatches the remote and steers the helicopter away from Ian, while the motorbike drives straight into Ian's groin. Simon and Theodore are about to forfeit the concert again, but Alvin and the Chipettes fly into the hall on the helicopter and they all sing We Are Family, winning the contest and the $25,000. Dave then comes back and watches them perform, along with Toby.
Meanwhile, Ian dresses up as Brittany, performing in the center alone while people boo him and he is dragged off-stage.
The Chipmunks and Chipettes sing Shake Your Groove Thing to end the night and go back home with Dave, while Toby himself goes back home. The Chipettes are re-adopted (although, this might only be temporary) at the boy's request and sleep at the Chipmunks' house where Dave has another injury. Dave tries to get Alvin to go to bed and Alvin refuses. So, Dave turns the lights off and Alvin turns them back on. Dave turns them off again. Alvin turns them back on while Dave says "Alvin, that's it! Don't make me come over there!" Alvin says "OK" while turning the lights off causing Dave to trip on the skateboard and crash. Alvin turns the lights back on and says "Ohh boy, I suddenly got really, really tired. Heh, heh, night Dave!" He turns the lights off and Dave yells "ALVIN!"

An epilogue shows Ian being thrown into a dumpster backstage by the guards and Ryan and his gang of Jocks being forced to scrape gum off of the gym's bleachers as punishment for the way they treated the chipmunks (and for making Alvin miss the battle).
