Three men sit around a table talking. Close shots of each one of them. Eyeglasses, lips moving, hands gesturing. The man with glasses swivels in his chair. Another man rocks in his chair, and beyond him is the sign that says “Neutral Conversation Only.” A woman with a stethoscope. A man with a stethoscope and a tape recorder. A group of men in an audience listen to a presentation. The man in the yellow shirt lights a cigarette.
