Robert Hanson (Jakob Cedergren) is a Copenhagen police officer transferred to a small provincial town following a nervous breakdown. Set to take up the mysteriously vacated job as town marshal, Robert quickly finds himself mixed up in a community governed by its own rules. Robert's big city temperament makes it impossible for him to fit in, or understand the uncivilized, bizarre behavior displayed by the townspeople: the sultry blond femme fatale, the ten-gallon hat and bolo-wearing town bully, and the sinister doctor with a penchant for maniacal cackling. Not to mention the bog, where things go to "disappear." TERRIBLY HAPPY quickly spirals into an intense fable reminiscent of the Coen Brothers' BLOOD SIMPLE and David Lynch's BLUE VELVET.
