A malfunction threatens to destroy Stitch and his friendship with Lilo!
Stitch has been having a series of bad dreams. They are a symptom of his incomplete manufacture of Dr. Jumba Jookibah's Experiment 626. Jumba was arrested for unauthorized genetic experiments before Stitch's molecules could be completely charged. Now Stitch is losing energy that causes him to periodically and unpredictably go berserk. He keeps unintentionally sabotaging Lilo's attempts to create an original hula dance for the upcoming Aloha festival. Jumba can track Stitch's dwindling resources and tries his best to build a new fusion chamber in which to recharge him before it is too late. Stitch has one too many outbursts for Lilo's patience, so she sends him away. Big sister Nani tries to comfort her. Lilo has been counting on winning the hula contest just like her mother had done when she was a young girl about Lilo's age.—Garon Smith
After everyone has settled in with the new version of the family, a technical problem starts to occur inside of a male alien creature. The technical problem makes him dangerous and a threat to the rest of the family. The family do everything that they can to fix before it is too late.—RECB3
Taking place between the original "Lilo and Stitch" and "Stitch: The Movie", "Lilo and Stitch 2" finds the rowdy extraterrestrial getting used to life with his new ohana. However, a malfunction in the ultimate creation of Dr. Jumba soon emerges, which reinstates his destructive programming and threatens to both ruin his friendship with Lilo and to short him out for good!—GigaCaesar
Stitch (Chris Sanders) is having nightmares about him reverting to his destructive self and hurting Lilo (Dakota Fanning) in the process. He tells Lilo all about his nightmares. Lilo believes that Stitch is afraid of turning bad again. They stay with Lilo's sister Nani (Tia Carrere). Along with Jumba and Wendy Pleakley (Kevin McDonald) (a Plorgonarian agent formerly employed by the United Galactic Federation, who assigned him as Jumba's assistant on Earth)
While at the hula class, Kumu (the dance teacher) announces that Lilo and her classmates will be prepared to perform at the local May Day festival. Each student is required to create an original dance. Lilo is inspired when Kumu tells her about her mother being in the festival at her age and winning, giving her a picture of the event. After the hula class ends, Mertle insults Lilo by telling her that she will never be like her mother, causing her to start a fight with her. However, after taking pictures of the brawl, Stitch forgets to flush the evidence. Kumu thinks that Lilo is not ready for the competition because of the fight with Mertle, but Lilo says that she is ready and "triple promises" to be good from then on.
It seems that after Stitch was created, Jumba (David Ogden Stiers) (a Kweltikwan mad scientist formerly employed by Galaxy Defense Industries who created Stitch, and now watches over him with the family they made on Earth) did not get a chance to fully charge Stitch's molecules before they were both arrested by the intergalactic police for illegal genetic experimentation. At first, this glitch causes Stitch to revert to his old destructive programming, but it will ultimately destroy him if Jumba cannot create a fusion chamber before Stitch's energy runs out.
Meanwhile, Stitch's uncontrollable destructive behavior is driving a wedge between him and Lilo and ruining her chances for success at the hula competition.Because Lilo is so concerned about winning the competition she fails to notice his glitch and does not understand that the trouble he is causing now is not his fault; she is too busy trying to get him to help her and completely neglects helping him.Eventually, the two devise a hula based on the legend of Hi'Iaka (who brought her lover back to life with the power of her love, when he was thrown into a volcano by a jealous goddess). Lilo gets increasingly angry at Stitch as he ruins their practice sessions.
To make matters worse Jumba is having problems creating the fusion chamber due to the fact that he does not have the proper alien technology to build it and has to try building it using ordinary house-hold objects.
However, just before the competition, Lilo and Stitch make-up and Jumba finally completes the fusion chamber. Then, Stitch has another one of his fits and accidentally scratches Lilo; this upsets him so much that he decides to leave Earth, believing himself to be "too dangerous". Lilo finally realizes that something is terribly wrong with Stitch and in the middle of her performance she forfeits the competition to help him.
As Stitch attempts to leave Earth, Lilo and the rest of the family desperately try to get him back so that they could re-charge him. Stitch then has another outburst which causes him to crash the spaceship in the Hawaiian mountains, Lilo rides over to the crash site in a mini space scooter, she finds Stitch close to death and struggles to get him into Jumba's fusion chamber. Unfortunately, she is too late by the time she places him in the machine and Stitch dies.
When a disheartened Jumba takes Stitch out of the chamber, Lilo holds him close and softly apologizes for her treatment of him, having finally understood that while she kept saying that she needed him, he needed her more. She says that he is her Ohana and, therefore, will always love him and breaks down in tears. Everyone grieves for a time as Lilo weeps, but Stitch eventually awakens, much to everyone's happiness. Pleakley is at a loss for words, to which Jumba explains what happened: Stitch was revived by Lilo's love.Later that night, the family (along with David) performs Lilo's hula dance on the empty stage, and Nani tells Lilo that their mother would be proud of her, and a star twinkles in the sky to justify.
