A group of students who have just started college win a school-sponsored trip to Las Vegas by plane. Unfortunately, they encounter a blizzard along the way. Unable to contact the ground, the plane has no choice but to make an emergency landing on a small island nearby.
During the descent, the plane crashes into a large tree by the roadside, severely damaging the fuselage. They also lose all contact with the outside world.
Stranded on this uninhabited island, they must face the dangers of nature and all kinds of beasts that went extinct long ago on this ancient land. Led by their class president, Tang Chao, they make their way out of danger, step by step, and escape the deadly swamp. They evade packs of wolves and defeat crocodiles. Just when they finally see hope, the unexpected happens.
A tribe of ancient cannibals discovers them, and they have no choice but to unite and face the savage outsiders together.
