A defense attorney has a crisis of conscience when he represents a wealthy client who has a foolproof plan to beat the system.

Mick Haller: I checked the list of people I trust and your name ain't on it.
Mick Haller: When do you retire, Lankford?
Detective Lankford: When do I retire?
Mick Haller: Yeah.
Detective Lankford: Eighteen months. Why?
Mick Haller: I wanna make sure I show up the next morning so I can kick your ass.
Earl: You know what? You would've done all right on the streets.
Mick Haller: Shit. Where do you think I am, Earl?
Earl: [picking Mick up from the hospital] You're nobody 'till somebody shoots you.
Eddie Vogel: [from trailer] Counsellor?
Mick Haller: Eddie, we had a deal. Either you pay me, or go with a public defender.
Eddie Vogel: How 'bout five grand?
Mick Haller: Ten.
[Eddie then hands Mick a brown envelope, presumably with money in it. Mick shakes the envelope]
Eddie Vogel: Ain't you gonna count it?
Mick Haller: I just did.
[last lines]
Mick Haller: I tell you what Eddie, how about I do this one for free?
Eddie Vogel: [gestures at him and leaves]
Earl: Are you sure you're feeling all right?
Mick Haller: Repeat customers, Earl. We'll stick it to 'em next time...
Eddie Vogel: You really shoot your client's mother?
Mick Haller: Damn right I did. She shot me first.
Mick Haller: [to the bikers beating up Louis] Hospital, not the morgue.
Eddie Vogel: How's it hanging, counselor?
Mick Haller: A little to the left.
Mick Haller: Maggie, you know what I used to be afraid of Maggie?
Maggie McPherson: Yeah, me.
Mick Haller: That I wouldn't recognize innocence. That it would be right there in front of me and I just wouldn't see it.
Maggie McPherson: Yeah...
Mick Haller: I'm not talking about guilty or not guilty; just, just innocence. Know what I'm afraid of now?
[Maggie shakes head]
Mick Haller: Evil. Pure Evil.
Frank Levin: [looking out of top floor window] You're so vain. Nobody would care if you killed yourself.
Mick Haller: It'd look cool. What do you think the last thing to go through your mind would be?
Frank Levin: Your asshole.
Mick Haller: Yeah.
Mick Haller: You know what my father always said about an innocent client?
Frank Levin: [sarcastically] No, I've never heard this...
Mick Haller: Do you know the difference between a Maserati and a Range Rover?
Reggie Campo: One is small and one is big, I guess.
Detective Kurlen: [to Haller in crowded elevator] How does someone like you sleep at night with all the scum you represent?
