Young men are whiling away the time playing cards. A stranger enters the room. The young men want to provoke him and pretend that an invisible lady has entered the room. They all court her and want to dance with her. After a while the stranger joins in their game. He asks the imaginary lady for a dance, begins to seduce her and has terrific fun doing so. The other participants in the game start to be puzzled by the behaviour of a man who seems to have gone mad, as if he can really see someone who doesn't exist. They escort the stranger out of the door. Then, they immediately go back to courting the imaginary lady.
