Underneath the ice. Underneath the skin.
Mary Jensen, a trained medic, needs a new start and she's getting one at Research Station Tau, in remote Antarctica. Called in as an emergency replacement, Mary soon finds out Tau's mission: to find a lost elementary particle, deep down in the ice.
Dr. Ian Schuller, the station lead, thinks the particle is the key to humanity's evolution. As they drill into the ice, complications arise and Mary starts to worry about his sanity. As he pushes harder and harder for results, the group begins to fracture.
And then the hallucinations start.
Something is in the ice, and it is changing them.
Now Mary must survive, and face what's underneath.
