He may be a cute dog to everyone who knows him, but Louie also loves learning about the American Revolutionary War from Buddy, who reads history books to him and takes him to historical sites. As towns and cities prepare for America's 250th birthday, Louie and Buddy visit Star Fort, a Revolutionary War battlefield in Ninety Six, S.C. In a strange series of events, Louie falls through the fort's abandoned tunnel and lands in Philadelphia in 1776, just days before the Declaration of Independence is announced. Now, Louie has a front-row seat to history and the war that is brewing in America!
