Detailed walkthrough
First, make your way up to Ranger Substation Osprey. You will encounter four White Legs guarding the prisoners. If you're a high enough level, one or more of them may be armed with anti-materiel rifles and/or brush guns. After defeating them all, as there is no peaceful solution, you need to open the cell to free the three prisoners, and therefore coplete the quest. To do this you can either unlock it with a Lockpick skill of 75 or more and simply pick the Hard locked cell door. Otherwise, the key can be found in a toolbox in the ranger substation tower, which you must ascend the stairs to obtain, then return and free the prisoners. This results in no less ecperience, except for the amount for picking the lock.
