Chris Miller, a Wall Street trading genius, once helped Lannister Capital survive the subprime crisis with his precise calls. Years later, as everyone embraces the AI boom, he spots a massive bubble built on leverage, circular financing, and fragile cash flows and decides to short the entire AI sector. But Mia, the new heiress running Lannister, mistakes him for an incompetent trader and fires him, even trying to blacklist him across Wall Street. Meanwhile, Kris Miller, a well-connected fraud, poses as the anonymous trading legend “King of Spades,” stealing Mia’s trust and control of Lannister’s trades. Backed by his college sweetheart Marina, CEO of Vesta Capital, Chris joins Vesta and rebuilds his old team. While the market goes all-in on AI, he bets against it. Despite huge paper losses, withdrawals, and ridicule, Chris holds firm. When AI firms begin defaulting and banks tighten lending, the bubble bursts, sending Lannister into a liquidity crisis while Vesta wins big. Kris’s fraud and market manipulation are exposed, and Mia realizes too late that “King of Spades” was actually Chris, the man she fired. Kris is arrested, Lannister collapses, and Chris returns as its new owner. At last, he and Marina reunite.
