Nani appears in the film, having become Lilo's guardian after their parents recent death. Nani is visited by Cobra Bubbles, a social worker, who is concerned that Nani cannot adequately care for Lilo. He is considering putting Lilo in foster care, but Nani refutes this, citing that she is the only family Lilo has. However, Nani will have to prove that she is capable of caring for Lilo, in order to prevent Lilo from going to a foster home.
After realizing that Lilo has no friends at hula school (the other girls bully her), Nani allows Lilo to get a pet from the pound. Lilo chooses Stitch, who, unknown to either girl, is actually an alien. Later, Nani is forced to take Lilo and Stitch with her as she tries to find a job. Unfortunately, Stitch's attempts to evade capture by Jumba keep ruining her chances. Nani's friend David, having seen Nani, encourages Nani to take Lilo surfing with them to inprove their mood. However, Jumba makes an attempt to capture Stitch from underwater. To everyone, it appears that Stitch had tried to drown Lilo. Mr. Bubbles sees the entire thing, and tells Nani he will come for Lilo in the morning.
While waiting for Mr. Bubbles the next morning, Nani is informed of a job offer by David. Nani orders Lilo to stay at home while she goes to apply. While she is gone, a fight between Stitch and Jumba results in the house being destroyed, and Lilo calls Mr. Bubbles for help. Nani returns at the same time as Mr. Bubbles arrives, and the two have a brief argument over Lilo's well-being. When Lilo is kidnapped by Gantu, Nani accompanies Stitch, who has revealed his alien origins, in Lilo's rescue. At the end, Nani and Lilo are appointed Stitch's wardens by the Grand Councilwoman, and Mr. Bubbles, who is a former CIA agent, is enlisted to supervise the new family.
