Based on the work of Erle Stanley Gardner, this drama series traces the origins of famed criminal defense lawyer Perry Mason (Matthew Rhys). The second season picks up with Perry in the throes of the Los Angeles legal system during the height of the Great Depression. Alongside crackerjack assistant Della Street (Juliet Rylance) and hard-boiled ex-cop Paul Drake (Chris Chalk), the former PI garners a reputation for taking on clients that few would dare to defend. Months after the Dodson trial shook the city, Perry is readjusting to life as a civil attorney when a high-profile murder case brings him back into the fold. As the DA homes in on a pair of brothers from a desolate Hooverville, Perry is thrust into the center of a vast conspiracy and forced to reckon with what it truly means means to be guilty.
