Dan Merrill is discharged from the fire department where he has distinguished himself because he is physically unable to stay in a smoking room. His enemies tell his girl, Mary Fenton, that he is a coward. But he proves his efficiency by trailing a gang of crooks who have been responsible for robberies in which they covered their tracks by starting fires.
