Set in the northeast corner of Alabama, on Sand Mountain and in the town of Fort Payne, "Three of Hearts" is based on a true coming-of-age story of a young man named Leo who is right out of high school and befriends a homeless man with artificial legs that lives in his car. But there's more to the man than meets the eye. As Leo begins to unravel the truth about the old man, he discovers a story so compelling that it draws him into the final chapter of a saga that began 15 years earlier when three wounded Vietnam soldiers made a pact, a pact they could never bring themselves to break.
