We accompany Sergio Colás, one of the best runners in the San Fermín bull runs, as he shares his minute-by-minute journey through Pamplona's biggest festival. We'll learn what it means to live a passion at all costs through the testimonies of those who know him best, and we'll delve into the intimate, everyday life of a man who lives for and by the bull runs.

Sergio, born deaf, has been able to break down those invisible barriers and prejudices that surround the lives of people with disabilities. For Sergio, being deaf and running in front of the bulls, in front of a crowd and at the most popular festival in the world, is not a handicap but an incentive. Sergio has managed to turn his disability into an ally when it comes to taking up running.

Furthermore, Sergio is a born fighter. His family, friends, and colleagues will reveal how Sergio is able to overcome obstacles that most people would find insurmountable. A story of self-improvement and self-affirmation, of optimism and risk-taking, that leaves a lasting impression on everyone who meets him.

Directed by Carlos Caro. Screenplay by Ismael Alonso.
