All the characters of the warm and fluffy "Lilo and Stitch" are back! In "Stitch! - The Movie", Stitch, Jumba, and Peakley are all living with Lilo and Nani. But no one knows that Jumba had secretly deactivated all 625 of his other experiments and brought them with him. The ex-captain Gantu, hired by Jumba's former partner, Dr. Jacques Von Hamsterveil, goes to find them, and captures Jumba to interrogate him into telling where they are. Now, Lilo and Stitch have to save Stitch's ohana from being used for chaos. Two experiments are activated in this movie: Experiment 221, "Sparky", with the ability to cause big electric surges, and Experiment 625, who has all the abilities of Stitch, but is lazier. At least he makes good sandwiches!—Anonymous
Stitch is still not fitting in and causes another disaster. Lilo tries to encourage him by saying he's one-of-a-kind, comparing him to Frankenstein's monster, which just makes him feel worse. Meanwhile, ex-captain Gantu, who's in his new spaceship after his original one got destroyed when he kidnapped Lilo and tried to recapture Stitch, is hired by a giant alien named Dr. Jacques von Hämsterviel to retrieve the other 625 experiments. Gantu goes to Earth, breaking into Lilo and Stitch's home, blasting Stitch into a net, finding and taking a blue pod with the number 625 on it, and abducting Jumba for interrogation. Stitch and Lilo take Jumba's spaceship and chase Gantu into outer space, engaging him in battle, only to be defeated and fall back towards Earth. Back at their house, Lilo, Stitch and Pleakley find the container Jumba was hiding. Pleakley realizes that these are the other 625 experiments, in dehydrated form, and warns them not to tell anyone or put the experiments in water, aware of how dangerous they are. Deliberately disobeying Pleakley's orders, Stitch and Lilo retrieve the container and hydrate one of the experiments, Experiment 221, who promptly escapes into the night. Jumba is being held captive on the ship of Dr. Hämsterviel, who is surprisingly revealed to be a diminutive creature resembling a cross between a hamster, poodle and rabbit, who had worked with Jumba in the past. Unable to intimidate Jumba, Hämsterviel activates another experiment, Experiment 625, to attack him. Although 625 has some of Stitch's powers, he is incredibly lazy and a terrible coward, prioritizing and making sandwiches above all else. Meanwhile, Pleakley is able to call Hämsterviel's ship via telephone. Hämsterviel tells Pleakley that he wants a ransom of the other 624 experiments in return for Jumba. When Pleakley informs the other family members what the ransom is, Nani proceeds to call Cobra Bubbles about the problem while Lilo and Stitch go out to find 221. When Cobra arrives the next morning, he seems to already know about what happened. Meanwhile, Stitch and Lilo finally manage to catch a troublesome Experiment 221 at a nearby hotel with a glass vase and soon befriend him. The rendezvous time arrives and Pleakley and Cobra show up with the container, not knowing that it contains only 623 experiments. Pleakley hands the container over to Hämsterviel, who is shocked to find that one is missing. Lilo then shows up with Experiment 221 trapped in the vase. Announcing that she has named it Sparky, she says that Sparky is part of Stitch's, and thus her, ohana. Furious, Hämsterviel tells her to give him the experiment or Jumba will die. After several moments of thinking and hearing Cobra, Pleakley, Jumba and Hämsterviel persuading them, Lilo and Stitch set Sparky free and break Jumba from his bonds. On Cobra's signal, the Grand Councilwoman's ship rises out of the nearby ocean and aims several guns at Hämsterviel to obliterate him. Lilo protests, saying that Hämsterviel has the other experiments while Sparky overhears this. Sparky then proceeds to use his electrical abilities to blow the power on the Councilwoman's ship, while Hämsterviel and Gantu climb back aboard their own ship with the captured experiments. In a last attempt to stop Hämsterviel, Lilo, Stitch and Sparky stow away on it as it leaves Earth. Inside the ship, Lilo and Stitch manage to swipe the container with the other experiments in it. The struggle for the container between Lilo, Stitch and Gantu results in releasing the dehydrated pods to rain down and scatter throughout Hawaii. Having captured the two, Hämsterviel reveals his plans to clone Stitch a thousand times over and orders Gantu to do what he wants with Lilo. While Gantu puts Lilo in a teleportation pod to send her to an intergalactic zoo, Stitch is strapped to a weight just heavier than he can lift. Watching as Stitch tries to avoid being vivisected by a laser for the cloning process, Sparky shows that he has reformed by short-circuiting the cloning machine. He then breaks Stitch free from his bonds and the two strap Hämsterviel to the device before they rescue Lilo.

Having locked Hämsterviel in handcuffs, Lilo, Stitch, and Sparky short-circuit Gantu's ship, causing it to crash near a waterfall on Kauai. Landing Hämsterviel's ship back at the rendezvous point, they give Sparky a new home powering Kilauea Lighthouse, which hasn't been running in years because powering it was very expensive. They then persuade the Grand Councilwoman to let them rehabilitate the other 623 experiments. The Councilwoman places Hämsterviel under arrest, and Jumba whispers to Pleakley that he has plans for making Experiment 627. At that moment, Experiments 202, 529, 455, 489, and 390 are activated, beginning the events of the series. Later, Jumba and Pleakley hope to go home with the Grand Councilwoman this time, but they are left stranded on Earth once again.
