It is up to the Scoobies to stop the Master's followers before they break the chain of slayers. Giles, Xander, Willow, and Buffy pursue the vamps back in time through the portal to save the slayers of the past. They must track the bloodsuckers from the French Revolution to the American Civil War without getting detected -- or worse!
But you can't change the past without changing the present. . . . -- From Amazon.com Product Description
