A father and his son walk alone through a post-apocalyptic America. Nothing moves in the ravaged landscape and it's cold enough to crack stones. Hoping to escape the endless winter, they head south towards the coast, not knowing what awaits them there. Along the way they encounter refugees, organized militants, and must avoid gangs of lawless killers. With the exception of a pistol with 2 bullets, the clothes on their back and a cart of scavenged food, they have nothing. All alone, the boys must struggle to survive in a world no longer capable of sustaining life.
