Marion, the telephone switch operator in a large factory, sticks to her post, notifying the different departments during the burning of the building. The fire department, of which Jack Watson, to whom Marion is engaged, is a member, received the alarm. Hastily the fire laddies get into their clothes and rush to the scene of conflagration. Everyone has escaped except Marion. Jack hears this, and tears himself away from his comrades, at the peril of his life, he dashes into the building and rescues his sweetheart. He drops with his precious and unconscious burden, exhausted, to the ground. They are each taken to their homes. When both are conscious, they are allowed to telephone each other, and their wedding day is set.
