The year is 1977, and America is finally getting over the nightmares of Watergate and Vietnam. But not everyone is ready to let it go. Not aging comedian Koo Davis, friend to generals and presidents and veteran of countless USO tours. And not the five remaining members of the People's Revolutionary Army, who've decided that kidnapping Koo would be the perfect way to bring their cause back to life.
