Synopsis: Angry villagers take the law into their own hands. Calling themselves "The Purple Vigilantes," they chase the bandits, thieves and killers out of town. When a few of the vigilantes turn out to be outlaws attempting to disrupt the group from the inside, the locals send for more help. To restore peace and bring justice to the area once and for all, Stony Brooke, Tucson Smith, and Lullaby Joslin (also known as The Three Mesquiteers) meet the call.
