The basic plot, without giving away too much, is that a young girl disappeared over two decades ago and new evidence emerges that reopens the investigation. Half of the story is told in flashbacks while the other half is conveyed by an actress just a few feet away from the audience. How it worked logistically was that we each sat in swivel chairs with headphones and a virtual reality headset. A scene would play in the headsets, and then a command with a countdown would pop up and tell us when to take off the headsets and watch the actress.
Some in my group found the virtual reality headsets a bit overwhelming and disorientating while others found having to step back and forth between the two worlds too much of a hassle. I found it to be incredibly interesting, and I loved how it enveloped me into the production.
