Movie Story : Kate Beckinsale plays Carrie Stetko, the lone U.S. Marshal stationed in Antarctica, who is counting down the days until she can leave the frozen continent for good. Just three days before the sun sets and the Amundsen-Scott Research Station closes for the winter, a corpse turns up on the open ice. The discovery pulls Carrie into a investigation into Antarctica's first homicide, a case that grows more dangerous with every clue she uncovers.
