In this loose parody of Dante's "Inferno," four Irish traditional musicians get lost in the backwoods of upstate New York the week before St. Patrick's Day. On the journey, the band descends through nine hellish circles of American-style 3/17 revelry: Step-dancing princesses. Bobbing shamrock headbangers. Green beer bacchanals. Shillelagh-wavin' geezers.
