From publisher blurb:
"The war between Earth and Mars raged for years and was devastating to both planets, although it never did reach a decisive conclusion. Tensions run high and each side still wishes to defeat the other, but neither side has been willing to commit more military forces to the conflict without possessing a clear advantage. It was for this reason that the Martians entered into an uneasy truce with Earth several years ago. Under the truce, neither side may execute a citizen of the other, lest war be unleashed anew. Instead, prisoners are interred in camps maintained by enemy forces."
The PCs find themselves in one such internment camp, subject to the nefarious machinations and undisclosed technology of its Martian masters.
