A twilight portrait that ultimately becomes a posthumous tribute to Cristóbal Halffter, one of the main compositional personalities of the last fifty years and a cultural and ethical reference. Through a kaleidoscope of statements and opinions of the protagonist himself and of composers, critics and also close friends, we get to know a Halftter who is both intimate and creative. His life trajectory is completed with performances by some of the best Spanish music interpreters in emblematic concert halls and sites in Spain.
