Sarah is a 16-year-old girl who is abused, emotionally abandoned and written off as just another hopeless causality of this world. Her mother's boyfriend, Roger, secretly involves Sarah in a sex traffic ring, and her mother, Karen, unsure of what to do, is afraid to stand up for her.
Sarah thinks she is beyond redemption and unworthy of love and is sent away from the house that defined her horrors to a place where she is not the only victim, or the only one fighting to get her life back, a ranch called Unbridled.
At Unbridled, Sarah meets Dreamer, a horse who has also suffered abuse, a horse who no longer trusts humans... That is, until he meets his girl, Sarah. Together, Sarah and Dreamer walk a difficult road and learn that family doesn't just happen, it's made with hard work.
They face many hardships and overcome terrifying obstacles, but in the end, Sarah experiences redemption and learns that love is the most powerful thing on earth. Together, they all learn to live Unbridled.
