After the sudden death of her husband, Nancy Botwin, a Los Angeles soccer mom, starts dealing marijuana to support herself and her two sons, Silas and Shane. The Botwins find strength in doing whatever it takes to protect each other, whether it’s Nancy sleeping with rival drug dealers to keep her business afloat, moving to keep the kids safe and away from the drug trade (even though Silas later joins the family business), or Shane murdering someone with a croquet mallet.
