Adapted from a patriotic poem by an English railway porter, Henry Chappell (sometimes known as the Porter Poet), was a propaganda film presenting German brutalities in Belgium.
According to Pike and Cooper, actor Johnson Weir, who adapted the play for the screen, would recite the poem during screenings.
