The Lost Souls motorcycle club of Owensboro, KY have always been the dominant club in Kentucky, until now, that is. With their President in jail and patch members dying, Ink (Charter Vice President) is forced to sit back and watch his beloved family fall apart. At least until he convinces Joker, Tanner, Hawk and Animal to become a prospects. They quickly become known as the Four Horsemen, and for good reason, as the bring hell to anyone who stands in the charter's way. On the brink of war with their rivals (the Rancid Riders), the Lost Souls must find a rat who is ready to go to the feds with information that will put a lot of Souls in prison, as well as a man from the Riders who infiltrated their club.
