Trinidad Pineda Chi?as from Oaxaca, Mexico learned at an early age that he was gifted, not with beauty or physical strength, but with willpower, the force of the spoken word and a constant eagerness for knowledge. The story of his life is a journey that starts with the whistle of a train, one that will take him to places he never imagined, where he will acquire infinite knowledge. It is also the place in which Trinidad's ardent speech to his railroad brothers resulted in a fight that would upturn a country and a regime.
