The Still Alarm (1926)

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. Later, Lucy reassures Richard that Drina has not been harmed and concludes that Dunn is unscrupulous. Richard forgives Lucy, and the two become reconciled.
