When a busload of seniors from a suburban Nashville church head down the Natchez Trace on a carefree journey to The Big Easy, they are unaware that a Mafia hit squad is playing a deadly game of tag with them. All except one passenger. The man they know as Bryce Reynolds is really Pat Pagano, a successful Las Vegas stockbroker who was lured into handling investments for a New York crime family. After his two grown sons are killed in an attack by a rival gang and his wife succumbs to cancer, Pagano decimates the mob with his testimony in federal court. He disappears, then resurfaces in Nashville as Reynolds, a retired businessman from Oklahoma. But after years of searching, an old Mafia capo tracks Pagano to the church bus en route to New Orleans.
