Eldon, Iowa. A tiny community in the heartland of America. A new state law bans sex offenders from living within 2,000 feet of schools, parks, public libraries, bus stops - anywhere children might gather. Charged with enforcing the new law, the local Deputy Sheriff is compelled to evict his neighbours' son. Over the course of a single weekend, fear and intolerance swell in the small town. The two men are thrown together to discover the ultimate price that each has to pay for safety.
