Rose of the Alley (1916)

When Tom Drogan drunken, wild ways, cause his mother's death, his sister Nell swears to protect and reform him. On the pretext of paying back a gambling debt, Tom brings "Kid" Hogan to the house, but ends up shooting him in the forearm. Dan Hogan, Kid's brother who is a policeman, rushes to the scene and catches Tom running away. To avoid arrest, Tom tells Dan that he fired at Kid for molesting Nell, and in the face of scandal, Dan and Kid back down. As revenge, Kid enlists Mamie, his girlfriend, to force Nell into a compromising situation with a man on a street corner. Conveniently placed, Dan arrests Nell for solicitation, but Frank Roberts, her boyfriend, arrives and extricates her. When Tom hears of the plot, he confronts Kid in a dance hall and soon a raging gun battle breaks out in which Kid is killed. Badly wounded, Tom seeks refuge with Nell, who prepares to protect him with his gun. As the police break down her door, Tom dies.
