The human race is engaged in a war with the Argoni, a ruthless alien war-species. On the outskirts of earth-owned territory, the colony planet Procyon One guards against an attack from the skies. However, the danger is closer than its inhabitants realize.
Landry Stanton alone knows of the impending disaster, but he and his coworker Cait Underwood are stranded miles from the outpost. Pursued by the Argoni, they must traverse the unforgiving landscape of Procyon One to sound the warning in time. Desperate, they delve into the secrets of the Argoni, but this risks both Landry’s life and his humanity.
Meanwhile, Marshall Evan Cole is blissfully unaware of the dire situation outside. He is called upon to lead a missing person case, but as the mystery is unraveled, Cole realizes that the outpost may be threatened by an enemy within.
Can Landry get to the outpost in time to save it from the hostile Argoni? Can Cole keep the outpost together long enough for them to fight off the alien threat? Or will the Argoni gain the final victory?
