Ten years after the Daxamites perished, Cadmus has been dismantled and Lillian Luthor is serving a lifetime sentence. Lena goes to an old facility of Cadmus, the last one she needs to shut down and destroy the weapons and other things that were designed there. What she finds, however, are not weapons, but children. The children are caged and appear to be made out of the DNA of a Luthor and a Super.
