From the cover of the adventure:
"Travel south into the goblin kingdoms is always frought with danger. Many go only as far as the Baron's outpost, Vakhund, the Watchdog Tower, and reside there in safety while merchants and others fare their way further down the road. But what happens when Vakhund Tower is attacked by goblins, orcs, and bandits? A noble is kidnapped, and only a dangerous trip into the dark,infested goblin kingdoms will reveal the answer."
