Patrick Bateman from American Psycho is charged for the murders of Paul Allen and "twenty, maybe forty!" other murders that he confessed to.
Since Patrick's regular lawyer has no idea who the **** Patrick Bateman even is, confusing him at various points for Patrick's colleagues Marcus Halberstram and Davis, Patrick's family hires an out of town lawyer to defend him.
Cue Saul Goodman, who jumps at the chance at defending a client as wealthy as Bateman.
Round 1: Saul aims for a not guilty by reason of insanity verdict. Can he do it?
Round 2: Saul tries to get Patrick acquitted for all of the murders. Can he do it?
Saul is in character in both rounds, and is willing to try whatever dirty tricks he can think of.
