Doc Ford's old friend, General Garcia, has gone into the business of smuggling Cuban baseball players into the U.S. He prefers high-profile collectibles, but when he obtains a collection of letters written by Fidel Castro in the early sixties, to a secret girlfriend, Garcia disappears, and then the man to whom he sold the letters. Doc Ford begins to investigate; he soon becomes convinced that those letters contain a secret that someone, or some powerful agency, cannot allow to be made public.
