Supergirl is called into action when remnants of the anti-alien terrorist organization Cadmus try to assassinate pro-alien leaders, but their endgame turns out to be much more sinister than she expected. J’onn relishes his peaceful new life, but an outing with an old friend causes him concern.

A shocking revelation causes chaos in National City. Supergirl sets out to capture Mercy Graves, while Alex takes control at the DEO.

Knowing how dangerous this makes her brother, Lena enlists the entire team – Alex, J’onn , Dreamer, Kelly and Brainiac – to help, but Supergirl realizes that the only way to truly stop Lex is to sacrifice herself.
