Previously, on "How To Get Away With Murder": Lots of murders, the least accurate depiction of law school ever, and sexy sexing for nearly everyone. See Episode 1 and Episode 2 recaps for more. Oh, and though it may be obvious: SPOILERS FOLLOW.
Episode 3 begins with more fun with the dead body (Prof. Annalise Keating's husband, Prof. Sam Keating), but mainly focuses on another case -- the hooker house mom who was once a domestic terrorist. If that (sans hooker) sounds like Patty Hearst, you and 300 fake 1Ls think alike, because they discuss the Hearst case and defense. This is your "defendant of the week" plotline, one that has no surprises whatsoever.
The real meat of the episode is WLW's (Wait-List Wes') possibly quixotic quest to help Goth Girl neighbor (Rebecca). The university is trying to get Keating's law firm to represent its star quarterback, who is quite obviously full of it and seems to have had something to do with the ongoing murder mystery (the dead girl from the first two episodes -- we know, there's a lot of murder in "HTGAWM"). WLW breaks the rules and does everything he can to rescue the reluctant Rebecca, but will he succeed?
