The Songrails, Robert and Edwina, have a house guest, Jane. A messenger arrives and informs the Songrails that Dora, Jane's bitterest enemy, is about to arrive for a visit. How do they avoid a war between the two in their quiet little home? Robert devises a way to get Jane to want to leave of her own accord by pretending that their butler, Sturridge, is deranged and bent on killing her. At the end, Sturridge has done the job, but is completely unaware of how valuable a butler he really is.
