Stranded in the middle of Antarctica, Concordia Station is so far from any point of civilization that it was dubbed "White Mars."

But the freezing temperatures and the prolonged isolation aren't the only problems that the crew has to face. When the research team returns with a new specimen discovered deep inside the frozen underground lake, things take a foul turn for the station members.

They don't realize how intelligent this lifeform is. They don't realize how long it lay dormant, waiting to be discovered; waiting for its opportunity to leave the ice and infect the world.

The choice that the remaining survivors on the station have is simple: stay quarantined with the parasite, or leave and doom humanity.
