From the introduction:
This adventure takes place in a mountainous area that has a chasm running through it and several gullies that split the rocky wilderness.
The complex on the map is currently occupied by a gang of bugbears who have kidnapped a merchant’s daughter and are holding her for ransom.
The local lord, having heard of the plight of the girl, has hired the party to take the ransom to the bugbears and escort the girl back to her family.
As well as this, there is a second gang of bugbears who were driven out of their lair by the hostage-takers and want to get it back. They will attack more or less as the party enters the lair to deliver the ransom and take custody of the girl.
