Diego de la Torre is officially an outlaw now, a full-fledged member of The Seventh Sons Motorcycle Club. The werewolf MC runs the wild lands of Sycamore with ease. At least until a dead body shows up and points to them as the culprits. Detective Maxim Dwyer presses the Seventh Sons hard, but there are other guns in play. California bikers look to expand their drug trade. A mercenary outfit seeks revenge. Top that with an overbearing FBI agent who undermines local police, and both detective and outlaw have their hands full. Brothers or not, Sycamore's about to get a whole lot bloodier.
