Set in the present day of 2026, the story follows a 25-year-old British food columnist and her colleague Georgia as they investigate a massive culinary revolution sweeping across Europe and America. What began in the 1990s as a New York pizzeria owner's Americanized take on Italy's fiery Diavola pizza, swapping traditional salami for pepperoni and standard chilies for jalapeños, exploded into mainstream culture by 2023, driven by social media, a collective fatigue with plain pepperoni, and major chains like Domino's and Pizza Hut standardizing the American Diavola on their menus by 2025.

The trend quickly sparked a fascinating trans-Atlantic reverse export. Italy, despite its notoriously strict culinary conservatism, embraced the jalapeño as the Pizza alla Diavola Moderna, comparing its integration to historical food revolutions like the introduction of tomatoes and potatoes. This Italian acceptance ignited a continent-wide spicy food wave: Spain sought to dominate jalapeño farming, France blended the chili with North African flavors, and chefs like Gordon Ramsay championed it in Britain, transforming local agriculture from the Netherlands to Turkey. As Georgia, the 25-year-old food writer, shares her sharp insights on how a single chili conquered Europe's most traditional tables, the two journalists realize they are witnessing a historic transformation of European cuisine that rivals the Age of Exploration.
