Annie Oakley

Two outlaws rob a stage, kill the driver and leave the shotgun guard for dead. The guard survives the attack and, with the help of a passerby, manages to make it to Diablo. The man can't defend himself from charges of robbery and murder because the bullet wound has caused complete amnesia. Annie and Lofty set out to prove the man's innocence.

After Annie thwarts a bank robbery attempt, young Smiley Douglas decides it would be a great joke to pretend to rob the bank the very next day without benefit of a weapon. Lofty fails to see the humor in the practical joke, but sets the man free. The outlaw gang who bungled their earlier attempt trick the trickster into helping them rob the bank yet again.

An miner's boastful letters to his grandson living in the East comes back to haunt him when the youngster announces he will be visiting the old man to learn more about his crime-fighting exploits. When the miner fails to prevent a jail break and causes him to lose face with the youngster, he recklessly decides to chase the escaping outlaws.

Della envies Annie's freedom and trick riding skills. When the rodeo comes to town, Della's father refuses to allow her to meet her boyfriend, one of the best competitors. When Della decides to run away, she falls under the sway of an unsavory couple, who agree to return to the ranch to retrieve her clothes. Actually, unintentionally armed with information Della has provided, the crooks plan to rob her father.

When a range war over water rights appears imminent, a masked man wearing a Robin Hood costume supporting the homesteaders knocks down ranchers' fences and stampedes stock. When an impostor dons a similar costume and robs the Diablo bank both sides demand that Lofty bring the criminal to justice.

A telegrapher's desperate message for help forces two murderous thieves to hide their loot in a box of bicycle parts meant for a pair of intrepid cross-country cyclists. The crooks force the cyclists to pedal their ill-gotten loot out of town, but Annie discovers their scheme and lays plans to capture the killers.
