"The point in history at which we stand is full of promise and danger. The world will either move forward toward unity and widely shared prosperity - or it will move apart." (President Franklin D. Roosevelt)

Six Time Patrol agents are sent to the same day, February 14, in six different years to keep our history and our time line from being destroyed.

Chicago, 1929 - gunmen massacre seven people in the infamous St. Valentine's Day Massacre.

1945 - President Roosevelt, heading home from the Yalta Conference, stops on the Great Bitter Lake to meet King Idn Saud of Saudi Arabia to discuss a relatively new topic: Arab oil.

1779 - Captain Cook, famed explorer of the Pacific, meets his fate in Hawaii.

278 - Saint Valentine is beheaded near the Milvian Bridge.

1945 - the Dresden Firebombing. Kurt Vonnegut is in a slaughterhouse as the first bombers appear overheard.

1946 - the ENIAC computer, programmed by six women, is unveiled to the public. The press thinks the women are simply models.

The mission, as always for the Time Patrol, seems straightforward: keep history intact, no matter the cost. But this time things go very differently than in previous missions, and one of the team members must make the ultimate sacrifice.
