Verona, Wisconsin, June 2000. A farmer vanishes in a hayfield and a driverless tractor rumbles down a country road.
The farmer is not the first to disappear in the field, so rumors abound. As days pass, the police lose interest, believing the man ran away to escape a failing family farm.
Seamus O'Neill, a rock & roll musician who never quite made it, sees things differently. While working part-time for a detective agency, he stumbles upon the tractor and becomes consumed by the disappearance. He sees clues which point to a sinister plot and develops a theory which explains the vanishing and the driverless tractor.
But can O'Neill find the missing farmer?
