Supergirl Season 4
In season four, Supergirl is facing a bigger threat than she's ever faced before – a new wave of anti-alien sentiment, spreading across National City that’s fomented by Agent Liberty. As Kara mentors a new reporter at CatCo, Nia Nal, and tries to use the power of the press to shine a light on the issues threatening to tear the city apart, Supergirl takes to the skies to battle the many villains who rise up in this era of divisiveness.
01. American Alien
Diving back into reporting, Kara welcomes a new cub reporter to CatCo. Meanwhile, James and Lena argue about James’ impending indictment for acting as the vigilante Guardian, while Alex and Brainy struggle to get in sync at the DEO. 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.
