In a new, predatory ice age, two brothers search for a place to call home.
The story centers on a boy who still remembers what life used to be like before everything turned to ice – a childhood of birthday parties and movies and after-school cartoons. As Jem clings to his childhood, the responsibility for their lives falls to Cody, the older brother. He stays awake each night, rifle in hand, making sure they survive to see the next morning.
This is a film about a younger brother forced to grow up faster than he wants to, and an older brother who will do anything to protect the brother he loves.
