'The distinction between the past, present and future is only a stubbornly persistent illusion.' Einstein. What does it take to change history and destroy our reality? Change events on the same date, 4 July, in six different years. The Time Patrol must send an agent back to each day, with just 24 hours for each to defeat the Shadow's plan to disrupt our time-line, creating a time tsunami and wiping our present out. Doc travels to the 4th of July, 1776, one of the most important dates in American history where forces are at work in Philadelphia to add a Declaration of Emancipation to the Declaration of Independence. Moms goes to Monticello exactly 50 years later, in 1826. The day on which two of the architects of that document and the country, Thomas Jefferson and John Adams, die within hours of each other.
