FX has debuted a new trailer for Sons of Anarchy, after the network announced last month that the hit series returns with the Season 6 Premiere on September 10. The video shows Jax (Charlie Hunnam) and other SAMCRO members riding past painted wall murals of Gemma (Katey Sagal), Tara (Maggie Siff) and Clay (Ron Perlman), which promptly explode as they pass by. What could this all mean? Are Gemma, Tara and Clay in serious danger? We'll find out for certain when Season 6 debuts next month, but, in the meantime, take a look at this trailer.
