Sergeant Preston of the Yukon

When Bobby Piggot's father dies and leaves him an orphan, he goes with Sgt. Preston to Sulphur City in the Yukon to live with his aunt and uncle. Later, two broke prospectors lure Bobby away from his uncle's trading post in order to rob it. When Bobby realizes their intentions, he breaks away and is shot. The prospectors go to the trading post, but Sgt. Preston has heard the shot and ends up there, too.
