Looking for a heartwarming alternative to this year's explosive cavalcade of summer movies? Then look no further than 'Quill: The Life of a Guide Dog,' a Japanese movie that tells the tale of a yellow Labrador Retriever guide dog paired with a sickly blind man who's reluctant to use him.

Originally released in Japan in 2004, the film chronicles the life of Quill the dog as he grows from puppy to full-fledged guide dog. Once he's trained to assist the visually impaired, Quill is placed with a blind journalist named Mitsuru Watanabe.

Watanabe is fiercely independent, though, and is skeptical of guide animals, preferring to use a cane instead. But Quill eventually wins him over through sheer determination and the two strike up a close friendship.

The tearjerker movie hits theaters domestically on May 18th. Watch the trailer above, but be sure to have a hanky at the ready.
