'Sgt. Stubby: An American Hero' is a computer-animated feature film based on the life and times of America's most decorated dog. After being rescued off the streets by a young Soldier on the eve of World War I, Stubby became the first canine promoted to the rank of Sergeant in American history. With 'The War to End All Wars' looming, a young Army doughboy Robert Conroy (Logan Lerman) has his life forever changed when a little dog with a stubby tail wanders into training camp. Conroy gives his new friend a name, a family, and a chance to embark on the adventure that would define a century. Narrated by Robert's sister Margaret (Helena Bonham Carter), Stubby and his new best friend quickly find themselves in the trenches of France and on the path to history. French poilu soldier Gaston Baptiste (Gerard Depardieu) befriends the duo and accompanies them along their epic journey through harsh conditions and incredible acts of courage.
