Aboard the Majestic Imperator Train de Luxe’s farewell run, Europe’s elite gather for one last glamorous journey. Owner Leo Goldberg hosts an extravagant show and private auction, selling the train to the highest bidder as it travels from Vienna through Budapest to Prague. Yet the Majestic is more than a luxury antique—it’s a secure, mobile platform with sealed compartments, few exits, and near-total anonymity, making it a magnet for spy agencies. A deep-cover Russian agent, MI6 operatives posing as honeymooners, Chinese agents quietly installing surveillance gear, and an ex-special forces officer with his daughter all board. Beneath the champagne and pleasantries, a covert struggle ignites. As the train races through the night, tensions climb, trust fractures, and escape routes vanish.
