The Randall family heads to Wisconsin for its annual summer vacation in picturesque Door County. It was to be a relaxing two weeks on Lake Michigan for Prescott, Jeanne and their three children. However, things do not go as planned. The Randalls soon find themselves in a town where peace and quiet are replaced by robbery, kidnapping and multiple murders. With each passing day, the violence draws closer to the family, until it affects one of their own.
