The Dispossessed

From publisher blurb:

Time has run out for the inhabitants of Vornath as the corporate owner of the moon forecloses on it and orders everybody off. The heroes are offered an opportunity to make some money providing transport for the colonists to the mainworld. But things take an unexpected turn when the company asks the PCs to make a last-ditch effort on their behalf to persuade a colony of holdouts to leave before corporate troops are sent in to remove them. The adventurers quickly find out that getting someone to leave their home without using force is a much harder task than it sounds.
