A group of men on a mission in the far reaches of space crash land on a savage planet, Earth. The only way their kind can survive here is to drink the blood of humans, which they take no pleasure in. On Earth they are known as "vampires". The youngest member of the group, Shae, encounters a teenage girl named Abigail, who challenges the group's loyalties to each other, endangers their survival, and steals Shae's heart.
