The Damn was a 24 hour, 240 mile bike race across the breadth of Minnesota, from South Dakota to Wisconsin- except for those who elected to double the mileage and bike back again to South Dakota. This film documents the final running of the race and the collection of characters from near and far- including one couple who chose to do the race on a tandem bike-- who found the challenge of biking through the night over gravel roads just the ticket.
