What would happen if a theatre company couldn't make it to the theatre in time to do the show? It would be a real problem to explain it to the public. But the theater director might have a brilliant idea. Ask someone else to act, "so much is a story that everyone knows", let alone those who have been editing the scenes of this show for years!
And this is how two technicians, accustomed to being behind the scenes, find themselves catapulted onto the stage to interpret the classic fairy tale, improvising actors.
