"El Cuarto Round" invites us to accompany Osvaldo, "El Mariana", on an intimate six-month journey as he prepares for his fight at La Velada del Año 4, at the Santiago Bernabéu stadium in Madrid. Through his training, we not only see him face physical and emotional challenges, but also discover new facets of himself, where his public and personal lives become deeply intertwined.
