Hachi, the legendary Japanese akita, proves that there is nothing more loyal than man's best friend in this modern retelling of a cherished true story. It all begins when a college professor adopts an abandoned dog named Hachi. The two form such a strong bond that Hachi walks with the professor to the train station each morning and returns to the station each evening to walk the professor home again. The routine continues until one day the professor does not return to the train station. Hachi, however, does not give up. He returns to the same train station at the same time, faithfully waiting for his owner to return. Hachi does this for more than nine years, until his own death.
