On paper at least...it will probably end up being good (not as good as McConoGawd's season of course) though so its all cool. Here is the rundown of casting, plot and character descriptions so far:
The Plot:
Possible casting and Character Breakdowns:
Vince Vaughn as Frank Semyon
A former thug turned businessman who’s working with a local Mayor and his political cohorts to spearhead the construction of a high-speed railway system that links southern California to northern California in order to reap financial gains from federal grants and land purchases.”
Elizabeth Moss as Ani Bezzerides
A tough, no-nonsense Monterrey sheriff whose troubled upbringing has driven her to gambling and alcohol. She reports to Sheriff James O’Neil and Deputy Sheriff Marla Simenon, and her partner, Elvis Ilinca, may have a crush on her. Ani also has both a hippie-type father who was absent when she was growing up, as well as a younger sister who isn’t afraid to show off her body. She’s also looking into the disappearance of former classmate’s sister.”
Colin Farrell as Ray Velcoro
Ray has been damaged by years of turmoil in both his personal and professional lives. A barely functioning coke-head with anger issues, he’s on Frank’s payroll and is battling his ex-wife for custody of their only son, Chad.”
Taylor Kitsch as Paul Woodrugh
A handsome, 28-year-old military veteran who has seen his own share of violence and destruction. He’s a motorcycle California Highway Patrol officer who’s put on leave after soliciting oral ex from a beautiful girl he pulls over for drunk driving. He reports to Commander Floyd Heschmeyer and has a Latino girlfriend he breaks up with when he’s assigned to the Caspar investigation.”
Michelle Forbes as Unknown
It’s possible she could play either Farrell’s ex-wife (a survivor of sexual assault) or Vaughn’s charming but mercurial wife.

The Plot:
“The second season of True Detective will follow the death of Ben Caspar, the corrupt City Manager of a fictional California city who’s found brutally murdered amidst a potentially groundbreaking transportation deal that would forever change the freeway gridlock in California. Three law enforcement officers from different cities and branches of the government are tasked with finding out who did it. They soon discover their investigation has much broader and darker implications than they initially thought.
Caspar’s 52-year-old corpse is found on a lonely stretch of the PCH near Big Sur—his eye burned out, genitals cut off and satanic symbols etched on his chest. It turns out he had a penchant for rough sex and may have been involved in the Occult.”
