On a rural Georgia farm in 1899, a lazy summer afternoon is interrupted by the arrival of a man claiming to be from the future. The stranger intended to provide the nation's forefathers with a letter detailing future events that lead to the demise of America in the 21st Century, but ending up in the wrong place at the wrong time, he has no choice but to leave the letter with the farmer.
Although no one ever believed the farmer's story about the visitor, he's afforded one last opportunity to recount the event with Theodore Garfield, a reporter for a local newspaper. But like everyone else, Theodore rejects the farmer's story and dismisses the letter's ominous warnings, including the prediction that America's gradual collapse will begin with the murder of a future American president named John F. Kennedy.
Years later, Theodore's encounter with the farmer is all but forgotten until a young senator named Kennedy is elected president. With the old farmer and his letter now long gone, will Theodore Garfield be able to prevent one of the most tragic days in American history?
