In a world where martial arts is both a sport and a combat, an expert in karate with a dark past confronts his inner demons once again. After years of inactivity, Alex, a solitary fighter who has left behind the struggle on his own, finds himself drawn into an underground tournament held in a secret temple in the heart of the city. This event, known for its brutality and lack of rules, brings together the best (and worst) fighters seeking revenge, glory, and above all, harboring crimes in their hearts.
While Alex tries to stay on the sidelines, his former partner, now a feared competitor, confronts him and forces him to reconsider his decision not to fight. Lured by the promise of substantial monetary rewards and the need to confront the men who betrayed his trust, Alex reevaluates his life and choices. Along the way, he encounters a diverse group of fighters, each with their own reasons for fighting, and an unexpected camaraderie develops.
As the battles intensify, Alex realizes that it’s not just his former partner who has unfinished business: there’s a darker enemy lurking who threatens to destabilize not only the tournament but his own existence as well. In this intense journey, the fight becomes more than physical; it's a struggle for redemption, to honor the past, and ultimately, to find his true place in the world.
