In the year 2166, a post Second Civil War America is finally back on its feet. Among the countless personal and cultural casualties of the war, the sport of baseball has been dead for over a hundred years. 12-year-old Joe Scott lives in the northern Illinois city of McHenry and goes exploring in the woods one day in a no man's land that a hundred years earlier was the site of the bloodiest battle of the war. While there, he discovers a relic from the distant past, from before the war. It sparks a search for its meaning. Little does he know that the wheels of Providence have been unwittingly set in motion which leads to a stunning discovery in Dyersville, Iowa.

This second discovery has a direct connection with the relic found in McHenry. As events unfold, Joe finds himself at the center of the rediscovery of a sport lost long and forgotten by the ravages of time and war. With no living person having any first-hand knowledge of the game, can he figure out the pieces of the puzzle to resurrect the game of baseball? Will his friends take to the game? What will the adults think?

Soon, the answers begin to unfold, and a magical sequence of events leads to an epic finale on a national stage!
