Island of the Blue Dolphins (1964)

A Girl's Incredible Adventure on a Lost Island!

This family movie tells of the true adventures of a young Native American girl.
After her father is killed by a malevolent white trapper, Karana (Celia Kaye)
joins her community as they leave their island home in the Pacific
to live on the mainland. Upon her departure, Karana realizes that
her brother has been left behind. She immediately swims back
to be with him and the two remain on the abandoned island.
Though Karana is able to domesticate a wolf, her brother
is not so fortunate with the animals and is killed by a
pack of wild dogs. She is left to survive against the
odds for several years before she has a chance
to journey to the mainland herself.
