Nim's Islandis a 2008 Australian adventure - fantasy film directed by Jennifer Flackett and Mark Levin and starring Abigail Breslin , Jodie Foster , and Gerard Butler . The story is based on the bookNim's Islandby Wendy Orr . A young girl, Nim, seeks help from the author of her favorite adventure series when her scientist father goes missing. Nim, though, lives on an island in the South Pacific. The author, Alexandra Rover, is an agoraphobic living in San Francisco . While Rover attempts to overcome her agoraphobic fears in order to set out in search of her, Nim tries to overcome her fear of losing her father. In the meantime, a cruise ship company attempts to invade Nim's island with uncouth tourists.

Nim ( Abigail Breslin ) is an 11-year-old girl, whose mother, Emily, has died. Her father Jack Rusoe ( Gerard Butler ), a marine biologist, said she was swallowed by a blue whale after it was scared by a ship called the Buccaneers. Nim lives on an island in the South Pacific and has some local animals for company: Selkie the sea lion , Fred the lizard , Chicca the sea turtle , and Galileo the pelican . Jack goes by boat on a scientific mission of two days to findprotozoa nim(a new species of plankton ); he wants to take his daughter along, but she convinces him that she needs to stay to oversee the imminent hatching of Chicca's eggs and can manage on her own; they will be able to communicate by satellite phone .

Nim, who is fond of Alex Rover adventure books (a parody of Alex Rider ) written by Alexandra Rover ( Jodie Foster ), receives an email addressed to her father with an inquiry about his field of knowledge. The sender "Alex Rover" seems to be the explorer, but is actually Alexandra, a neurotic San Franciscan who constantly sees her character Alex Rover (also Gerard Butler). An email conversation follows, where Nim first poses as her father's assistant and then goes to the volcano on the island to see what's inside it and is hurt in the process.

Jack suffers a shipwreck, which makes it impossible for Nim and Jack to communicate. Also, he does not return on the planned date. Throughout the movie, Galileo brings Jack things he needs to fix his ship. Nim explains the situation to "Alex". Although Alexandra suffers from agoraphobia and therefore never leaves the house or even opens the door, she travels to the island to rescue Nim.

The island is visited by tourists, taken by Nim to be pirates . Without exposing herself, she scares them away by catapulting lizards at them and making it look like a volcano is about to erupt. One of the tourists, a young rich boy named Edmund, follows her and sees her. He is confused by her presence, and believes her to be another tourist. But when he tells the others, he isn't believed and is punished by his parents for leaving them by removal of his GameBoy and television for a month

The tourists leave. Alex arrives by helicopter at the tourists' boat and tells them about her rescue mission. The tourists do not believe that a girl is on the island, but Edmund tells her what he had seen. Encouraged, Alex goes to the island and is saved by Nim from drowning when her boat gets trapped in a large monsoon rainstorm and is wrecked. When the storm clears up, at the island, Alex introduces herself. At first Nim doesn't want her to stay, but eventually allows her. Later Jack arrives on a raft still holding the plankton, and falls in love with Alexandra.
