BBC Play of the Month S12 E07 Heartbreak House

On the eve of World War I, Ellie Dunn, her father, and her fiancé are invited to one of Hesione Hushabye's infamous dinner parties. Unfortunately, her fiancé is a scoundrel, her father's a bumbling prig, and she's actually in love with Hector, Hesione's husband. This bold mix of farce and tragedy lampoons British society as it blithely sinks towards disaster.
