A parody/spoof film about an anti-American documentary filmmaker (a la Michael Moore) who tries to abolish the 4th of July holiday because America is evil. The ghosts of John Kennedy and General Patton take him through the past, present and future to help him to understand that the terrorists really are the bad guys.
As spoofs go, it's not bad. Kelsey Grammer is amusing as slap-happy Patton, and Trace Adkins is the no-nonsense Angel of Death. There's even a cameo by Whiskey Falls.
It's an amusing bit of fluff. Amusing, but easily forgotten.
