Each season involved parallel plot lines that intertwine and overlap, centering on both the personal and family life of Jackson "Jax" Teller (Charlie Hunnam) and on SAMCRO (Sons of Anarchy Motorcycle Club, Redwood Original). SAMCRO is involved with gun-running in the western United States, and deals with rival gangs, politicians and the authorities. As vice president and later president of SAMCRO, Jax struggles to manage the club and the legacy of its founder, his late father John Teller. He is frequently at odds with his stepfather, Clay Morrow, who has taken over the club since John's death, and is also now married to Jax's mom and John's widow, Gemma Teller Morrow. Jax also grapples with his relationships with his high school sweetheart, Tara Knowles, and his best friend, Opie Winston.*SAMCRO is said to emulate the Hells Angels Motorcycle Club; the series includes special guest appearances by David Labrava (Happy), Chuck Zito (Frankie Diamonds), Rusty Coones (Quinn), and Sonny Barger (Lenny "The Pimp" Janowitz) who are real Hells Angels members.
