It's simple, really. You take a small town in Indiana, make it an excruciatingly hot and humid Wednesday in late July, of 1937, add a young boy named Johnny Dawson; give him something he doesn't know he has; make it something the Nazis desperately need in order to conquer the World, and you'll have The Story: John Dawson's story.

He'll be chased. He'll be captured. But, with the help of a witch, and the World's Greatest Knife Thrower, and her father, the World's Foremost Authority on Time Travel, Johnny will escape and use a Time Machine to send his Nazis pursuers into a time vacuum for fifty years.

Now, those fifty years have come and gone. The Nazis are back. They want John Dawson and the Time Machine. They want to use it to turn back the clock to 1937 and then rewrite the course of History.

Realizing the Nazis have discovered where he lives, John Dawson knows he needs to disappear. But before he does, he also knows he has to share The Story (his story) with his grandson, Tommy Dawson. He needs Tommy to know what happened back then, because Tommy is going to have to find that Time Machine and destroy it.

Destroying it was something John Dawson could have done, should have done, but didn't do.
