Poll of the Week: First contact disaster

Your vessel has been chosen for the important mission of first contact. The species is due to launch its first manned warp engine flight in a month, and they have already launched several warp probes to neighboring uninhabited star systems.
A duck blind has been in place for several years, and its team leaders are in the process of removing themselves from the population. They have given you many reports on the culture, and of the current political state of the planet. They report that the people of this world are likely to have a mixed reaction to the knowledge that other life forms exist in the universe. While many would accept it, the research teams report that the working class, as well as the planet’s military forces would likely respond with xenophobia due to popular belief and rhetoric.
One of the duck blind teams fails to report in, and your operations officer is unable to locate their biosigns or the dermal communicators implanted in each of them. After a week of searching other teams report strange communications about captives being taken by the military. Looking into those communications it confirms the missing team is indeed being held in an underground government controlled facility.
You can not beam in or out of the facility directly, and have little choice but to reveal your presence to them in order to rescue your team. As captain what do you do? Tell us in the the Forums!
This is a new question from our category “Morals of Trek,” where you are in the shoes of a Starfleet captain facing a dilemma any of our favorite characters could have faced in Star Trek. If your crew has faced any such dilemmas and you want to see it featured in a Poll of the Week, let us know!
