The Green Wall Said

Five human beings find themselves seated in a semicircular room and surrounded by an illuminated green wall. 

Looking around for his clinic, an Australian doctor questions his sudden change of scenery. A prisoner wearing a gray jumpsuit likewise questions his new surroundings.  Unnerved, a helicopter pilot exclaims that they are inside a flying saucer. An accountant pleads with his unseen captors for freedom, and a nun identifies her order.
