Two days before the 50th anniversary of the assassination of President John F. Kennedy, rookie FBI agent Jake Miller is on his way to meet some friends at a football game at RFK Stadium. But Jake has one stop to make first. A quick meeting with a crackpot who called the FBI claiming to know who "really" killed JFK. The caller turns out to be a 70-year-old Frenchman who says he fired the fatal shot from the grassy knoll. Now sure that the man is crazy, Jake is trying to ditch him when four guys in dark suits--real "Men in Black" types--show up to take the old guy into custody. What happens next will turn Jake, the crazy Frenchman, a beautiful FBI intelligence analyst, and a kook conspiracy writer into the targets of a massive federal manhunt--and the only people who can stop another high-profile assassination.
