In the charming small town of Hamilton, New York, home of Colgate University, Burt Marshall is a well-known figure. He prepares taxes and sells insurance to many residents, sponsors local youth sports teams, and is frequently seen riding his bicycle on Main Street. When clients visit Burt's office, a sign on the wall offers an enticing deal: Invest with him and earn 8% return. Nearly 1,000 people take him up on the offer. But the neighbor that everyone knows and loves is hiding a dark secret.
