Activate (The Ravagers - Episode One)

Centuries of calamities took humanity to the brink of extinction. Now, with the aid of a time capsule, the human race is once more populating the Earth, resurrecting technologies lost centuries earlier. With those innovations, though, come civilization's need to fight for control. Just as humanity seemed poised for a return to stability, they'll learn that some among them seek a return to extinction. They need only find the right time, and the right person, to put their plans in motion.
