In this true story, a baby male killer whale gets separated from his family in a remote Vancouver Island fjord. When the lone young orca seeks companionship from people he becomes beloved. This documentary shows what happens as years pass and the whale becomes both treasured and feared. To Native Americans he is the spirit of a chief; to boaters he is a goofy friend; to conservationists he is a cause; to scientists he is trouble; to officials he is a danger. As conflict and tragedy stain the waters, Luna becomes a symbol of the world’s wildest beauty: wonderful to know, but so hard to save.
