Caution: Contains strong language, blood, violence, armed force and other things that occur in a post-apocalyptic world without laws.
More than 15 years ago humanity was almost completely wiped out by a virus. Since then Alex tries to survive with a small group, because the humans, who didn't die at that time, mutated into dangerous monsters.
One day, an unpredictable dangerous man named Tyler appears and forces Alex to travel to San Francisco with him and a few other survivors to loot the abandoned city. As soon as they are on the move, Alex gets into situations that he usually avoids at any cost to save his friends and his own survival.
