In this touching family drama, Kacie Lewis is a rebellious 17-year-old girl struggling with guilt and anger after witnessing the death of her younger brother. When Kacie is arrested and sentenced to a work-release programme at Spirit Riders, an equine therapy camp, she is clearly out of her element. However, she finds a kindred spirit in Blaze, a retired racehorse. Under the guidance of the ranch's no-nonsense owner, Kacie helps retrain Blaze and in the process, learns how to let go of the past, forgive herself and set her spirit free.
