The Cloud Rider

Plot: Bruce Torrence is an aviator and member of the secret service. His rival for the hand of Zella Wingate is Juan Lascelles, a drug smuggler. To get rid of Torrence, Lascelles loosens a wheel on one of his planes, but Zella is the one who goes up in it. Torrence goes up in another plane and attaches a fresh wheel to Zella's plane. In spite of his efforts he later finds her in Lascelles' arms.
