Polaris VI Antarctic Research Station. The winterers are getting ready for the long polar night as the summer crew flies back home. Johan, the summer commander, says goodbye to his wife Annika. She’s staying behind to complete her research alongside Arthur Wilde. Six months later, Johan returns to the base to find seven dead bodies, two missing… and only one survivor. Annika is one of the two persons unaccounted for. Johan needs Maggie to remember: it’s his only chance of finding his wife before it’s too late.
