We are in Tehran in 1958, and Nasser Ali Khan, one of Iran's most revered tar players, discovers that his beloved instrument is irreparably damaged. Though he tries, he cannot find one to replace it, one whose sound speaks to him with the same power and passion with which his music speaks to others. In despair, he takes to his bed, renouncing the world and all its pleasures, closing the door on the demands and love of his wife and his four children.
