FX on Tuesday picked up Sons of Anarchy to series for a September launch.

The cable network handed out a 13-episode order to the drama from The Shield writer/executive producer Kurt Sutter, FX Prods. and Fox 21, which is set in the world of motorcycle clubs.

The news comes days after HBO began production on the pilot for its own biker-themed drama, 1%.

According to The Hollywood Reporter, the show, which Sutter is exec producing with father and son Art and John Linson, explores a notorious outlaw motorcycle club's efforts to protect their town of Charming, Calif., from drug dealers and local corporate developers. It centers on Jax Teller (Charlie Hunnam), whose love for the brotherhood comes into direct conflict with his growing apprehension regarding the club's lawlessness. Katey Sagal, who is married to Sutter, stars as his force-of-nature mother. The other central role, that of Jax's stepfather, who is the club's president, will be recast. It was played in the pilot by Scott Glenn.

"Doing research, I had the opportunity to spend time with members of outlaw motorcycle clubs," Sutter said, "and was amazed at how the outside world takes them seriously and within their fraternity, they have a great sense of dark humor and don't take themselves seriously."

Sutter is planning to infuse more of that dark humor into the script, which led to the reimagining of the stepfather character and the recasting of the role, he said.
