On a near-abandoned research base in an Arctic ice field, a skeleton crew works to ensure the centre doesn’t collapse amid treacherous storms. Officially, Trieste Grayling arrives in order to explore and film a sunken shipwreck for a documentary film; privately, she's working through a complicated grief. Trieste soon realises she's not the only one who was attracted to this intense isolation in order to escape her ghosts. Each of the crew members harbour dark secrets: Mal, the ever-competent medic conducting mysterious therapy sessions, Sweetie, the reclusive engineer with scarred hands, Thorsteinn, the aloof diver tender, Avelina, the temperamental base manager whose stories of home don't quite add up, Grace, an underwater welder and recovering addict, and Judd, the erratic former member of a ‘90s boy band. As they begin to reach breaking point, each one's hidden ghosts finally comes into the light.
