A college football quarterback on his way back to class stumbles upon his zombie classmate feasting on their dead professor and realizes that the world as he knew it has been completely destroyed.
Zack Holloway's scared. He's confused, he's disoriented. He asks himself what's going on. But he doesn't know. It's not like anyone's alive to tell him anyway. Just a short trip to the bathroom, a welcome break from the geology class that puts him to sleep and his world is turned upside down. He sees things that defy explanation: His classmate eating his professor, his professor getting up, shrugging off fatal injuries and coming for him.
Zack knows he must get out of this nightmare. But when he's inadvertently trapped in the faculty building by a fellow survivor, he soon discovers that the living may be even more dangerous than the monstrous undead.
