Tv Season Info

Season 4 of the drama series opens with Kara (Melissa Benoist) going back to her reporting job at CatCo while still working with the DEO, proving that she can both be a superhero and have a normal life. Meanwhile, an attempt on President Marsdin's (Lynda Carter) life exposes her as an alien, causing chaos in National City; Mercy (Rhona Mitra) and Otis (Robert Baker), the siblings responsible for the crime, manage to escape and become a threat to the DEO. With humans becoming more and more anti-alien, Kara and her friends try their best at showing that aliens and people with superpowers aren't dangerous but can be exceptional allies against forces of evil.
