It's set in an apartment where the electric lights are out for most of the play.
The play is written to be staged under a reversed lighting scheme: the play opens on a darkened stage. A few minutes into the show there is a short circuit, and the stage is illuminated to reveal the characters in a "blackout." On the few occasions when matches, lighters, or torches are lit, the lights grow dimmer.It was fun to read, but I found the characters so unappealing
that I was left with an unhappy feeling.
