For most of the evening, you're exploring the rooms of a large multi-storied house. Almost all of the rooms have an inhabitant of the house who will engage with you either alone or in a small group. You do see the other audience members and even interact with them, but mostly, you're connecting to the other house members one-on-one.
Its also sort of a adventure game. The evening is propelled by a series of "quest" of finding and delivering objects to the various characters. There is a arc to the evening's events, and its a lot of fun figuring out what's going on, but mostly you're wandering around a surreal lucid dream. Its quite intense at times, but also very empowering and magical.
