"Thunderhead," a roving, big white stallion, causes problems for the Wyoming ranchers when he leads their blue-blooded racing mares off to join his wild horse herd in the mountains. Escaping gunfire, he runs off one night with a young rancher;s mare, a possible winner of the Governor's Stake trotting race. The mare is recaptured and entered in the race against the horse owned by the father of the young rancher's sweetheart, and this puts a damper on their romance. 很想看。 根据Mary O'Hara的小说改编的剧情影片，当在怀俄明州的农场的荒芜大草原上设法求生与时，人和动物其实地位是均等的。影片以一个农场主的侄女爱上了邻家农场主的儿子的爱情故事为中心，而关于马的故事又是紧跟一匹桀骜不驯的公马及一匹名为“雷云”白色的母马开展..
