Watch Nim's Island

Nim lives on a South Pacific island with her father, Jack Rusoe, who is a marine biologist. After her mother was swallowed by a blue whale, Nim buries herself in her animal friends, ranging from Selkie the sea lion to Chica the sea turtle. When her father discovers a new and rare species of plankton, he implores her to set sail with him but she insists she needs to remain behind to witness the hatching of Chica's eggs.

Nim receives emails addressed to her father from the famous adventurer, Alex Rover of the Alex Rover adventure novels, not realizing the writer "Alex Rover" is actually a neurotic woman, Alexandra, posing as an explorer. A big fan, Nim responds to the message as her father's personal assistant and agrees to visit the volcano "Alex" is interested in researching.

Meanwhile, Jack's ship has wrecked and he is unable to communicate with his daughter. Nim can't get a hold of her father and fears him dead, realizing she can't save her home without the help of adult. Agoraphobic Alexandra learns of the danger and bravely leaves her apartment to help Nim save the beautiful island.
