[1] The plot is detailed in The Moving Picture World magazine as follows:[2] Tom Drogan, addicted to gambling and drink, is the object of a good mother's devotion.

His sister, Nell, is much more susceptible to her mother's good teachings, and has grown like a flower among weeds, with a great affection for both and an innocence that marks her apart entirely from her surroundings.

He has been sent by Nell for the doctor and in his inebriate condition has forgotten all about the ill mother, and has been induced to go into a saloon and indulge further, finally remembering his errand and bringing the physician too late.

He finds him, with his girl, in a cheap dance hall, and there their respective gangs engage in a fight, in which several guerrillas are killed, while others make spectacular getaways.

While the pursuing officers are hammering the door in, Tom drops the revolver, and Nell picks it up, crazed with the single thought of protecting her brother, just as she had promised her mother to do.
