The secret's all out regarding Season 2 of HBO's award-winning series "True Detective." It has been confirmed that actress Rachel McAdams has been tapped to play one of the lead roles in the second season of the show. Variety said that McAdams will play Ani Bezzerides, a Ventura County Sheriff's detective who will be at odds with the system that she serves and the rest of the characters involved in the show. Her character will reportedly clash with a corrupt detective named Ray Velcoro, which will be played by Colin Farrell.

HBO also confirmed that aside from McAdams, Taylor Kitsch and Kelly Reilly will join the cast as well. Kitsch will play a highway patrol officer and war veteran Paul Woodrugh while Reilly will be seen as a former D-list actress and wife to a mob boss named Frank Semyon. Vince Vaughn will reportedly play the mob boss and the husband of Reilly's character.

Flavorwire said that the plot for "True Detective" Season 2 is not yet clear, but it will certainly involve a transportation conspiracy. An excerpt of The Hollywood Reporter article based on its interview with series creator Nic Pizzolatto read, "The scripts he's working on when we meet have four leads, three of them cops, one of whom is female, but that, too, is likely to change. He refuses to even comment on the logline making the talent agency rounds, which likens his premise to Chinatown, with a brutal murder set against the backdrop of a potentially groundbreaking transportation deal that would change California's freeway gridlock forever. All he'll say is that it's a "work in progress," and that if he talks in any detail about what he's doing he loses the urge to do it."

HBO has yet to confirm the release of the second season of "True Detective," but a Variety post earlier stated that it might be slated for a January premiere.
