If anyone understands the phrase "tough luck," it's Harrison. As a foster kid in a cruel home, he knows his dream of one day playing in the NFL is a long shot.
Then Harrison is brought into a new home with kind, loving parents-his new dad is even a football coach. Harrison's big build and his incredible determination quickly make him a star running back on the junior high school team.
On the field, he's practically unstoppable. But Harrison's good luck can't last forever. When a routine sports injury leads to a devastating diagnosis, it will take every ounce of Harrison's determination not to give up for good.
