Coogan is injured by a delayed blast. Brown, his employer, refuses aid when requested by Mary Coogan. Nellie Coogan, following her mother, meets Beth, Brown's daughter, who has strayed from home. Beth forgets where she lives, and Mary, returning from Brown's, ignorant of Beth's identity, takes her and Nell to the Coogan home. Left alone, the children eat headache pills, and when discovered are seriously ill. Both are put to bed and Mary is again dispatched to Brown to tell that Beth is dying. The Browns, after a night at Coogan's, forget caste, and Brown's indifference of a few hours before dispels, and he recognizes the law of humanity.
