Watch the 'Sons of Anarchy' Season 4 Promo (VIDEO)

The season four promo for "Sons of Anarchy" has hit, and it's looking like there's going to be plenty of mayhem in the coming season.

The gang is out of jail, but the war against the cops is heating up...the promo shows an on-the-road scuffle between the bikers and a cop car with the cop spinning off the road, while another clips shows one side of a pretty serious gunfight.

"Sons of Anarchy" is the highest-rated original program on FX in the network's history, and the cornerstone of its new set of original dramas going forward (with the help of "Justified").

The show premieres this fall (check out the FX Fall Preview schedule to find out when) along with returning shows "It's Always Sunny in Philadelphia," "Archer" and "The League," as well as new show "American Horror Story" from "Glee" creator Ryan Murphy.
