On the final journey of the legendary Majestic Imperator Train de Luxe, Europe’s elite boards for a farewell voyage. Owner Leo Goldberg stages a glamorous on-board show and private auction as the train travels from Vienna to Prague via Budapest, selling the Majestic to the highest bidder. But the train is more than a luxury relic: it is a controlled, mobile platform with secure compartments, limited exits, and near-total anonymity. That makes it irresistible to intelligence agencies. A Russian agent under deep cover, MI6 operatives posing as newlyweds, Chinese agents secretly wiring the train for surveillance, and a former special forces officer traveling with his daughter all converge on board. Behind champagne and polite conversation, a covert war unfolds. As the train speeds through the night, the stakes rise, trust erodes, and escape routes disappear.
