The town of Greenridge is a small, picturesque community that prides itself as being the Mayberry of the Midwest. It is a peaceful place, surrounded by farms, forests, and tranquil countryside.

Without warning, the world around them appears to go mad. Something is modifying human DNA, enhancing the Warrior Gene. Those who are infected lose their inhibitions, become extremely aggressive, and ultimately believe in their own superiority. Almost half of the population is affected.

Within days of the outbreak, the government crashes, the military collapses, and society fails.

With their slow pace of life brutally interrupted by the apocalypse, the residents of Greenridge are forced to band together and take up arms. It will require all of their skills, courage, community spirit, and love for each other to survive.
