The Triplets of Belleville

Kidnapped by mysterious square-shouldered henchmen, a Tour de France cyclist named Champion is spirited across the ocean to the teeming metropolis of Belleville. His grandmother and faithful dog follow his trail and are taken in by a trio of eccentric jazz-era divas. The motley sleuths follow the clues to an underground betting parlor and now the chase is on!
