Goblins form a large part of the workforce in the depths of Sharn in Eberron, working the foundries and factories in very poor conditions. They're not actually locked up or anything (usually), but they don't have much in the way of prospects either.
It'd be pretty easy to set such an adventure there, and then you have the rest of the city available to explore once they do move on from the factory.
