When Jack meets the odd Dr. Nigel Stone he takes his theories for just that, unrealistic ramblings of a mad man. Before long Jack learns that not only are Dr. Stone's theories of time travel real, but he will become part of them, slipping in and out of time at his leisure he will take part in and experience some of histories greatest moments as those who actually lived them did. Jack also learns that experiences of the past don't have to be great or of epic origin in order to be life changing.
