Micah is a resourceful junior high-schooler living in a modest city apartment with his overworked single mom and older brother, Leo. On a walk to school one morning, he encounters a stray American Bully pup--later named Ghost--who has a tough past and an even tougher life surviving on the streets. Despite his mom's warning that they can't afford a pet, Micah becomes determined to prove he's responsible enough and earns money his own way.
