A prequel series for The 100 is coming to The CW!
THR reports that the pilot will air as a planted episode in the upcoming and final season The 100, which is filming now.
The untitled drama is set 97 years before the events of The 100 and starts with the end of the world and a nuclear apocalypse that wipes out most of the human population on Earth.
It follows a band of survivors on the ground as they learn to cope in a dangerous world while fighting to create a new and better society out of the ashes of what came before.
