Blue Blood

In the small town of Sycamore Ridge live youthful sweethearts Bob Hendricks and Molly Culpepper; Bob's banker father, General Hendricks; and John Barclay, head of the Golden Belt Wheat Co. When Adrian Brownwell comes to town to publish a newspaper, his cash deposits in Hendricks' bank relieve the banker's worry that an expected bank examiner will discover the shortage in bank funds resulting from Hendricks' support of Barclay. Adrian falls in love with Molly and decides to leave Sycamore Ridge when she refuses to marry him. Barclay threatens Molly with the financial ruin of many whom she holds dear unless she marries Adrian, and Bob returns from the East to find Molly the new Mrs. Brownwell.

Lucy Bostil, daughter of a Colorado ranch owner, is led by a dog to his master, Lin Slone, who is exhausted from a struggle to capture a wild horse; she revives Lin and they christen the horse "Wildfire." The Bostils have entered Sage King in a race, but Lucy agrees to tame and train the wild horse, since Buckles, her favorite colt, has been stolen. When Joel Creech, a half-witted stable hand, is discharged, he becomes a tool of the Cordtses--who also have entered a horse (Buckles) in the race--in drugging Sage King. Lin and Lucy enter Wildfire under the Bostil colors, and she rides him to victory, When Cordts is disgraced and discovered to be a horse thief, he persuades Joel to abduct Lucy. Joel does so, but first he kills Cordts. Warned by his dog of Lucy's danger, Lin pursues and rescues the girl.
