Harvard professor of symbology Robert Langdon arrives at Bilbao's ultra-modern Guggenheim Museum for a major announcement - the unveiling of a discovery that will "change the face of science forever". The organizer of the social evening is the 40-year-old billionaire and futurist Edmond Kirsch, who has become a globally recognized personality thanks to his dazzling super-modern inventions and bold predictions. After the social event begins, Langdon and several hundred other guests are completely captivated by the very original presentation; however, a carefully planned evening suddenly turns into chaos, and Kirsch's rare discovery threatens to be lost forever. Langdon is forced to flee Bilbao in imminent danger; he is accompanied by Ambra Vidalová, the elegant director of the museum, who helped Kirsch stage a provocative social event. Together, they go to Barcelona on a dangerous mission: to find a mysterious password, with the help of which they will reveal Kirsch's secret. However, an insidious enemy stands in their way, who will stop at literally nothing...
