You never know what is hiding inside you...

Is all scientific research for the good of mankind? An amazing June night. A peaceful mansion surrounded by forest, where a happy family prepare for a dinner. Human guinea pigs, modified to become a real weapon escape an illegal clinic appear in the same forest. A family who has bonded instinctively together in order to protect each other from harm, or genetically altered, callous humans. Who will survive the onslaught?
