It has almost been a year since the world ended. The majority of the population died, came back as mindless and highly aggressive creatures and killed most of the rest. Cody is one of the last survivors. He is small, sensitive, innocent and about to starve to death. While he is desperately trying to find food, he gets attacked and then saved at the last second by Troy, who is a hardened brute. Cody hates him, but knows he is probably his only chance to survive the winter, so he sticks with him.
