"Mr. Robot," according to the industry paper, "centers on a young programmer, Elliot (Rami Malek), who suffers from an antisocial disorder and can only connect with people by hacking them. A mysterious anarchist named Mr. Robot (Christian Slater) recruits Elliot into 'fsociety,' an underground hacker group determined to bring down corporate America."
