Rick's police cruiser has finally run out of gas and there's not a fueled up station for miles, if one exists at all. He walks part of the way before finding a horse in a barn. Together, they ride on to Atlanta, which turns out to be worse off than Rick's home. Hordes of zombies quickly devour Rick's horse and attempt to do him in as well, but he's saved by a mysterious man in the city. The two escape from the zombies in Atlanta and make it out to the countryside. The two continue travelling until they reach the survivors camp, where Rick's wife and son are.
