It's January 1993 and winter is fast approaching the National Science Foundation outpost in Antarctica. While the small team there -- led by Dr. Andy Harrison (GERARD PLUNKETT) and including survival guide Jerry Shepard (PAUL WALKER) and cartographer Charlie "Coop" Cooper (JASON BIGGS) -- would normally be getting ready to leave with the approach of winter, their plans are changed when pilot Katie (MOON BLOODGOOD) flies in with geologist Davis McClaren (BRUCE GREENWOOD).
He's searching for a meteorite in a remote section of the continent, but since the ice is still thin, they won't be able to take the snowmobiles there. Instead, Jerry will have to accompany Davis on the expedition where the transportation will come in the form of Jerry's dogsled team. Led by pack matriarch Maya and veteran Old Jack, the rest of the team includes Shorty, Dewey, Truman, Shadow, Buck and the rookie husky, Max.
As they make their way for a remote mountain, an immense winter storm quickly approaches, thus cutting their expedition short. After barely avoiding a catastrophe, Jerry, Davis and the dogs make it back to the base camp. Along with the others, they then receive orders to evacuate, but due to limited space on Katie's plane, they can't take the dogs. Thinking he'll be able to return in a few days, Jerry goes along with the plan, but then learns that everyone is being evacuated off the continent altogether.
Distraught and worried about his dogs that they leashed to a chain at the outpost, Jerry wants to go back to get them, but is overruled and eventually finds himself back in the U.S. From that point on, and as the days, weeks and then months pass, he does what he can to convince anyone to help him get back to Antarctica and try to rescue his dogs.
