Factory girl Joan Dodd (Medina) and Jack Fowler (Hanley) are in love and expect to marry in due course. When Jack is called up for war service however, Joan's socially-ambitious mother (Ellen Pollock) seizes the chance to meddle in her daughter's life by encouraging the attentions of Joan's older boss Adolphus Pickering (Claud Allister), who is infatuated with her. Pickering proposes marriage, and under pressure from her mother, Joan accepts.
