Prestigious architect Emil Zarco receives the most important commission of his life, an ambitious urban project with which he can showcase his ideas on the essence and purpose of men: that we are a long lineage destined to perpetuate itself in search of progress and the betterment of our capabilities. In the same city, another man travels in the opposite direction: seeking to disappear and to break with a society that does not acknowledge him. He doesn't speak. El Mudo (the Mute) wants no company. Emil and el Mudo are damaged: one by the loss of a son and the other by the impossibility of having one. The city is both the witness and the scene of their battle, against their own demons and for the love of a woman.
