Krissy heard someone scream her name just as a car crashed into her leg and sent her flying. After bouncing off another car, she fell headfirst onto the hot asphalt parking lot. She didn't feel any different at first, but mentally, things started to change as she recovered. She began to crave violence. Revenge against the driver that hit her became her number one priority. Rich, her husband, was reluctant at first, but he soon joined in her murderous schemes to satisfy her cravings. Dave Nissen was a seasoned, hard–nosed detective. As the top detective on the force, he was put in charge of investigating the deaths of two men found dead after being in contact with Rich and Krissy Stevens. He pushed his other cases aside and put all his efforts into bringing Rich and Krissy to justice. He vowed to do anything and go anywhere to catch the murderous couple, even the jungles of Mexico.
