What if Jackie Kennedy was pregnant when JFK was shot? "The Last Great Hope" is the account of a retired Secret Service agent named Stone who was at Dallas on November 22, 1963, and was subsequently assigned to adopt out a mysterious baby under an assumed name. Forty years later, his megalomaniacal boss, whom he refers to as Top Dog, calls Stone out of retirement to search for the missing Kennedy child. His journey across the U.S. also includes his own coming-out process. As a still-handsome man in his 60s, he winds up in San Francisco and meets Jeremy, a younger man who is searching for the perfect "Daddy."
