Dolphin Tale.  Rated PG.  Inspired by a true story, Dolphin Tale is about courage, ingenuity, and never giving up.  Sawyer is a young boy who's struggling with school and doesn't have many friends other than his cousin Kyle.  When Kyle, a star swimmer, joins the army to earn money for college and is called to active duty, it looks like Sawyer is destined to spend his summer alone tinkering in the garage and attending summer school.  Sawyer stumbles upon a dolphin that's been severely injured, becomes fascinated by dolphins, and is suddenly intellectually engaged like never before.
