After the Gulf Coast is battered by three tremendous hurricanes, a deadly virus breaks out, turning the infected into mindless, blood-thirsty zombies. Within hours, the plague has spread throughout most of Texas and shows no signs of slowing down. San Antonio police officer Eddie Hudson finds himself in the middle of the outbreak, along with a few other survivors. Eddie does his best to fight off the zombie horde and locate his wife and son, who he believes still are safe and haven’t been infected by the virus.
