Based on a true story, "The Banker" centers on revolutionary businessmen Bernard Garrett and Joe Morris, who devise an audacious and risky plan to take on the racially oppressive establishment of the 1960s by helping other African Americans pursue the American dream. Along with Garrett's wife Eunice, they train a working class white man, Matt Steiner, to pose as the rich and privileged face of their burgeoning real estate and banking empire - while Garrett and Morris pose as a janitor and a chauffeur. Their success ultimately draws the attention of the federal government, which threatens everything the four have built.
