Charles Bunbury (GRAMMER) is the bumbling, affable chairman of Tuftons, a historic bank based in London. Chairman more in name than in practice, Bunbury married into the position and spends most of his time on the golf course. But when a rogue trader leaves Tuftons skating on thin ice, Charles must transform himself from a labrador of Liverpool Street into a wolf of Wall Street to save the company from rival American and Japanese banks. In a risky move, he ends up breaking the bank, losing both his wife and her family fortune in the process. At rock bottom, Charles’s only hope of saving the bank and winning his wife back is a homeless, self-taught financial wizard and his estranged, anti-capitalist daughter. It’s not much of a team, and they don’t have much of a plan, so it’s probably just as well that Charles doesn’t understand how shorting and hedging might win him the day.
