What's the basic premise of the series?
The premise is pretty dumb. Basically a 20something with a photographic memory impresses a hot shot lawyer enough to hire him. They fake his college/law school transcripts so he can work under him.
Once you get past that the show is pretty awesome.
I'm guessing it's cutthroat corporate lawyers, but what do they do each week?
Sort of. They have a storyline that carries over throughout each season, but also through in some 1 episode clients that cases are usually resolved by the kid genius discovering some hard to uncover facts or the hot shot lawyer being a baller.
There's also power struggle inside the firm, threats from outside the firm, and the fear of being discovered as a fraud. It's actually a pretty awesome show.
