"Sons of Anarchy" will be back for a 13-episode sixth season in September, and FX has released a stylized teaser promising nothing but conflict, below. Kurt Sutter's motorcycle club drama is one of the network's flagship series, and is likely to run at least another season. Meanwhile, in this upcoming one, Jimmy Smits is set to return as Mexican-American gangster Nero Padilla, as is Donal Logue (who's been guesting on "Copper") as the antagonistic former U.S. Marshal Lee Toric.
