The plot centers on the doomed love between Beatrice Granger, a young Welsh schoolteacher, and Geoffrey Bingham, a barrister trapped in a miserable London marriage. Their connection ignites when Beatrice heroically rescues Geoffrey from a canoeing accident during a violent storm. However, their path to happiness is blocked by a trio of obstacles: Geoffrey’s gold-digging wife, Honoria; a wealthy but obsessive suitor named Owen Davies; and Beatrice’s own sister, Elizabeth, who is determined to steal Davies for herself.
