Among the guests are a group of people who really can’t stand each other: Holly, a struggling diversity consultant who continuously clashes with everyone until she gets a migraine, and Danny, a quick-witted talent agent that name-drops his client list every chance he gets. As the evening begins to unravel and dark secrets are revealed, waitress Niamh finds herself right in the middle of their chaos.
