Black Comedy is a one-act farce by Peter Shaffer, first performed in 1965. The premise of the piece is that light and dark are transposed, so that when the stage is lit the cast are supposed to be in darkness and only when the stage is dark are they supposed to be able to see each other and their surroundings. A young sculptor and his fiancée have borrowed some expensive antique furniture from a neighbour's flat without his permission to impress an elderly millionaire art collector. When the power fails, the neighbour returns early, other people also arrive unexpectedly, and matters descend into near-chaos. Source: Wikipedia (en)
