A Cry for Help.

Knocked down by an automobile, the intoxicated tramp is taken to the doctor's house, received and treated to a square meal. The husband of a patient has just died, calls on the doctor, intending to kill him. The grief-crazed man is foiled several times by the return of the tramp, whom the maid at last pushes out of the house. She hears the doctor struggling with his assailant and faints. The tramp hears the doctor's cry for help and enters by a rear window, despite the objections of a policeman, in time to save his benefactor.
