A group of friends gather at an Airbnb on New Year's Eve. It is Benjamin's birthday, and his sister Abigail is throwing him a jazz-age Murder Mystery themed party. As the night plays out, champagne is drunk, hors d'oeuvres consumed, and relationships forged, consolidated or frayed. Someone kisses the wrong person; someone else's heart is broken. In the morning, all of them wake up -- except Benjamin. As Abigail attempts to wrap her mind around her brother's death, an eminent detective arrives determined to find Benjamin's killer. In this mansion, suddenly complete with a butler, gardener and housekeeper, everyone is a suspect, and nothing is quite as it seems. Will the culprit be revealed? And how can Abigail, now alone, piece herself back together in the wake of this loss?
