In the twilight of his life, the brilliant but tormented inventor Alfred Nobel finds himself haunted by a legacy he never intended. When a premature obituary brands him a "merchant of death" for his invention of dynamite, Nobel, portrayed with profound depth by Héctor Alterio, is thrust into a crisis of conscience. This introspective drama, directed by Fabio Carpi, weaves together the pivotal relationships in his life, including his complex bond with his brother and the influential presence of peace activist Bertha von Suttner, played by Katja Riemann. As Nobel reflects on the destructive power his creations have unleashed upon the world, he embarks on a deeply personal journey to redefine his existence and seek redemption. The film masterfully explores the weight of guilt and the desperate human desire to leave a mark of peace, rather than war, culminating in the genesis of an idea that would forever change history. With a stellar supporting cast including Stanislas Merhar and Giovanna Mezzogiorno, this biographical drama presents a poignant and atmospheric portrait of the man behind the most famous prize in the world.
