Sharod (Paul Walker) and his friend Cooper (Jason Biggs) and the eccentric geologist (Bruce Greenwood) formed an expedition team with eight sled dogs to search for a meteorite in the icy Antarctic. When they first arrived in Antarctica, the snow was so white that the three of them were amazed, but they did not expect the coming snowstorm at all. The harsh weather and dangerous environment in the Antarctic made them walk on thin ice. One of them accidentally stepped through the thin ice and fell into the piercingly icy water. Fortunately, the sled dogs rescued them and escaped the danger
Sudden snowstorm stopped them from moving forward. In desperation, the three chose to abandon the sled dogs and pigeons to escape, and the eight sled dogs struggled to break free from the ropes and escape , In order to keep out the cold and rely on each other, they have to fight with seals to fill their stomachs. After the three of Xia Luode returned to the safe base, they remembered the sled dogs who were desperately protecting them, and couldn't be relieved, so they made up their minds to turn back along the way to find them, and vowed to return to the safe base with their loyal companions.
