The Cloud Rider (1925)

Aviator and Secret Service agent Bruce Torrence is ordered to arrest Juan Lascelles, who smuggles narcotics using a fleet of airplanes. After Juan sabotages Bruce's plane by loosening a wheel, Zella Wingate, the woman desired by both men, takes it into the air. When Bruce sees the wheel fall off, he straps a spare to his back, gives aerial chase, transfers to the plane in midair, and bolts the wheel in place. Bruce later discovers Zella in Juan's embrace and quickly realizes that he is really in love with her sister, Blythe. Juan captures Bruce and Blythe and takes the latter hostage in his plane. The agent frees himself and gives chase, while Blythe tampers with the controls on Juan's plane, causing it to crash into the ocean. Bruce leaps into the water, captures Juan, and rescues Blythe. The lovers are married and leave on an aerial honeymoon.
