Jessica and Jane have been living together for six months and are devoted friends - or are they? Jessica loves her friend with the cruelty of total possessiveness; Jane is rich, silly, and drinks rather too many brandy-and-sodas. Watching from the sidelines, their friend Sylvester regrets that Jane should be 'loved and bullied and perhaps even murdered by that frightful Jessica', but decides it's none of his business. When the Irish gentleman George Playfair meets Jane, however, he thinks otherwise and entices her to Ireland where the battle for her devotion begins.
