The Still Alarm.

Lucy Fay leaves her husband, Richard, a fireman, for a suave politician, Perry Dunn. Richard compensates for the loss by adopting Drina, a baby girl whose mother perished in a fire. Drina develops into a beautiful young lady and becomes a model at a modiste shop owned by Dunn and managed by Lucy. Dunn is attracted to Drina and plots to get her alone by giving her a drugged drink. An untimely fire interferes with his plans, leaving Drina drugged and trapped by flames in Dunn's room, where she is sleeping.
