Sons of Anarchy is an American television drama series created by Kurt Sutter about the lives of a close-knit outlaw motorcycle club operating in Charming, a fictional town in the Central Valley of Northern California. The show centers on protagonist Jackson "Jax" Teller (Charlie Hunnam), the then-Vice President of the club who begins questioning the club and himself.
One of the best shows. Great acting, especially Claire Danes is wonderful and beautiful as always. If you like thrillers, you should definitely give it a chance. It's almost impossible to watch only one episode.
