Horses, motorcycles, a learning disabled little brother, and possibly a girlfriend, complicate Randy's life. He thinks he has outgrown his pony; competing in arenacross resulted in a debilitating leg injury; his little brother commands his parents' attention; and his girlfriend - if she is his girlfriend - fights a battle with cancer. He is a teenager trying to find maturity surrounded by circumstances that are spinning his life out of his control. Yet, Randy has an anchor. Boomer, the pony he thinks he has outgrown, remains a constant in his life, and she is ready to teach him that pain and loss are not insurmountable. Boomer and Randy enter the world of competitive carriage driving, demonstrating that she is a for always pony.
