Red Nails begins in the jungles far to the south of any known civilized or barbarian kingdoms. Valeria of the Red Brotherhood is fleeing persecution after she murdered a would-be rapist. She is followed into the wilderness by Conan, a fellow adventurer who wishes for an alliance with Valeria as her lover. Conan's stand-off with Valeria is interrupted by a dragon which mauls their horses.
Red Nails is the last of the stories featuring Conan the Cimmerian written by American author Robert E. Howard.
