This season revolves around a motorcycle gang headed by Jackson Teller, his mom Gemma and his step father Clay. All three of them are noticeable individuals in the gang who also owns an auto shop and does artillery trading.
There are enough compelling pieces here, and the setting is novel enough - this is a different type of organized crime than what you usually see on TV - that Sons could eventually be a worthy heir to The Shield.
A powerful drama dealing with many unpleasant topics - from gun running to vigilante justice. I haven't seen anything quite like it on television in years.
