Unexpected alliances form while others unravel, setting the stage for a sudden and shocking turn of events that leaves everyone at the estate questioning their relationships and motives. Throughout this intricate social dance, sharp observations on class distinctions and human nature are made, highlighting the intricate, often hidden connections between the upstairs aristocrats and their downstairs service staff.
