Táto vojnová sága sa odohráva v drsnom vesmírnom prostredí, kde ľudstvo čelí neľútostnému boju o nadvládu. Sledujeme osudy vojakov, ktorí musia v nehostinných podmienkach bojovať o prežitie a plniť rozkazy, ktoré často spochybňujú ich morálku. Séria skúma témy obete, odvahy a ťažkých rozhodnutí, ktoré musia hrdinovia urobiť tvárou v tvár ničivému nepriateľovi. Je to pútavý príbeh o prežití a ľudskosti v extrémnych podmienkach.
The USA reigns over Earth as the last surviving superpower. To build a society free of American influence, foreign countries have inhabited the moon. Under orders from the US military, Sergeant Ethan Stark and his squadron must train to fight a desperate enemy in an airless atmosphere.
Ethan Stark is placed in command of the US military forces that have overthrown their high-ranking officers. Instead of issuing orders, Stark confides his hope of forging an army based on mutual respect. Now, in addition to fighting a merciless enemy on the moon, Stark must contend with the US government's reaction to his mutiny.
He was sent into space to protect the US Lunar Colony. Instead, when faced with orders that would do nothing but get his soldiers killed, Sergeant Ethan Stark lead a rebellion. Now he and his soldiers must fend off deadly aggression from their own country without igniting a full-scale civil war.
