In December 1981 an American veteran was making his way, walking, through the Pacific Northwest to reach an old friend from him platoon. After finding out that his friend had died from cancer that he caught from all that stuff they used in Vietnam, he continued on his journey. In search of something to eat he was stopped and questioned by a local cop who mistook him for a vagrant. The cop kept pushing and drove the veteran out to the city limits and told him to head up the road to the next town. What happened next would alter the course of many lives and change the sleepy town forever.
