Reckless Courage (1925)

Doris Bayne is instructed by her wealthy father to deliver a valuable diamond necklace by air. When the airplane is robbed in flight, Doris is forced to throw the necklace from the craft's open cockpit, and it lands at the feet of Bud Keenan, an honest ranch foreman. Bud picks it up and soon finds himself looking down the barrel of a pistol held by Doris, who has parachuted from the plane. Doris ties up Bud, but he escapes and rescues her after she falls down an embankment. Bud takes Doris to his ranch, but while he fetches a doctor, gang leader Scar Degan appears and demands the necklace, which Doris has given to a Native American woman for safekeeping. Scar takes Doris to the gang's hideout, forcing Bud to retrieve the necklace and buy her freedom. A battle follows that leaves the gang dead and Bud in possession of the necklace, which he returns to Doris.
