In the mid-24th century the vampire threat is so terrible that humanity is on the run and their numbers are dwindling. The only ones willing and able to fight the vampire plague are those in The Order.
In addition to creating specialized vampire-killing weapons, The Order has protected all the world's leading scientists. They're rewarded with the ultimate breakthrough: time travel. But there's a catch -- if you return to your present time, your mind doesn't come home with you.
Now a select team will be sent back to the Middle Ages, to stop the vampire threat before it can spread. They're the best vampire slayers of their day and age, but once they go a thousand years into the past they're strangers in a strange old land. Their perfect weapons aren't working right, their numbers are too small, and the vampires seem to know who they are. It will take the ultimate leap of faith for the team to have a chance to complete their mission -- and survive.
