The year is 1899 in New Orleans, and Mardi Gras celebrations are underway. Parade floats fill the streets and each evening, various Krewes throw lavish masked balls. You’re invited to the Calypso Ball, the inaugural ball hosted by the first-ever all-female krewe.
The guest list is varied, as Calypso has invited one of the oldest all-male krewes, Sinis, to attend their exclusive soiree. The identities of the members of both Calypso and Sinis are a mystery, and are guarded heavily by each krewe. Masks are essential to concealing each person’s identity as they all convene for an evening of anonymous exuberance and decadence. But when a man in a gold mask takes a fatal tumble down the stairs, it’s quickly realized that a devious plot is afoot. The guests’ heavily-guarded identities must be revealed to find out who killed the man in the gold mask, and why!
