Supergirl
S04E18 Crime and Punishment
Kara and Lena visit Stryker's Island in search of information on how to take down Lex. Inside the prison, Kara attempts to connect with a curious inmate named Steve, who might know what Lex has been up to, while Lena examines a series of puzzles left by Lex in hopes of locating him. Chaos erupts as a prison riot breaks out, and Kara must find a way to manage the situation without exposing her Supergirl identity. Meanwhile, Kelly urges James to seek help for his PTSD, and Alex confronts Ben Lockwood after he invades the DEO to obtain powerful weapons aimed at hunting Supergirl.
