After the Second World War, Preston Tucker tried to start a car company to challenge the big Detroit auto makers. His prototypes were impressive. Sleek cars with engineering innovations such as seat belts long before they were mandated by the government, Tucker's cars generated a wave of excitement. However, the political muscle of the Big Four Automakers (General Motors, Ford, Chrysler, and American Motors) doomed his project. This film is the story of Tucker's efforts and ultimate failure.
