After a jaw-dropping season 6 finale, "Sons of Anarchy" is back with another explosive season that promises a darker path for SAMCRO after the gruesome death of Jax's wife, Tara. Now on its final season, the outlaw biker series released a new exclusive trailer that features Charlie Hunnam as SAMCRO's president vowing not to lose his club after losing his wife's in a brutal murder.

Vowing vengeance for SOA season 7, Jax will start morphing into the Grim Reaper 10 days after Tara's death in the new trailer, Bad Place. The less than one minute video features Jax's son, Abel, asking Gemma if his dad has done some bad things, and just like any mother, the SAMCRO's matriarch defended her son.

Charming's new sheriff played by "The Bridge" actress Annabeth Gish will be confronted with so much chaos as she works hand in hand with Wayne Unser, the fictional town's previous sheriff before Sheriff Roosevelt was killed by Juice to cover-up Tara's death. Gish will be playing Sheriff Jarry who will start working with Jax's biker club for the murder investigation of both Tara and Sheriff Roosevelt.

Other newcomers who will be walking in the streets of Charming includes Marilyn Manson, who will play as the white supremacist Ron Tully, Courtney Love as Abel's new teacher and Lea Michelle as a truck stop waitress who bonds with Gemma. Drea de Matteo is back to reprise her role as Abel's mother and Walton Goggins is going to show his sassy side for reprising his role as Venus Van Dam.

While working for the final season of his show, SOA lead star, Charlie Hunnam, is Guy Ritchie's pick to play the iconic role of King Arthur in the upcoming Warner Bros project. A perfect excuse for dropping his role as Christian Grey in the upcoming racy movie "Fifty Shades of Grey," Hunnam is already an established actor who got a franchise role in Guillermo del Torro's movie "Pacific Rim."

"When you see Hunnam as Jax Teller leading the Sons into the final, brutal revenge filled final season, I think you'll agree that he has all the intensity necessary to play King Arthur, and that this is a better post-Sons course for him than playing the S&M fetishist billionaire Christian Grey, a role that Sutter and I agreed is better suited to a newcomer than an established actor on the cusp of movie stardom," Deadline's Mike Fleming reports.

"Sons of Anarchy" season 7 is scheduled to kick off on Sept. 9 on FX.
