he Piano tells the story of a mute Scotswoman, Ada McGrath (Holly Hunter), whose father sells into marriage to a New Zealand frontiersman, Alistair Stewart (Sam Neill). She is shipped off along with her young daughter Flora McGrath (Anna Paquin). The voice that the audience hears is not her speaking voice, but her mind's voice. Ada has not spoken a word since she was six years old, expressing herself instead through her piano playing and through sign language for which her daughter has served as the interpreter. Ada cares little for the mundane world, occupying herself for hours every day with the piano. It is never made explicitly clear why she ceased to speak. Flora, it is later learned, is the product of a relationship with a teacher whom Ada believed she could control with her mind, making him love her, but who "became frightened and stopped listening," and thus left her.
Ada, Flora, and their belongings, including the piano, are deposited on a New Zealand beach by the ship's crew against her angry objections. As there is no one there to meet them, they spend the night alone, sheltering under a tiny tent made of a hoop skirt frame. The following day, Alistair arrives with a Māori crew and his friend Baines (Harvey Keitel), a fellow forester and a retired sailor, who has adopted many of the Māori customs, including tattooing his face and socializing with the Māori instead of his own race (save Alistair). There are insufficient men to carry everything and Alistair abandons the piano, again eliciting objections from Ada. Wikipedia
