Presented by Jeremy Isaacs.
Professionals wield a great deal of power. What motivates them? What attitudes and ideas lurk behind their job titles? To whom are they accountable? Psychiatrists with Dr Jeremy Holmes Dr Timothy Crow and Dr Brenda Morris. Tonight Jeremy Isaacs confronts the professional world of three psychiatrists. One woman in six and one man in nine will spend some time in a psychiatric ward. Millions more need psychiatric help as outpatients and live off repeat prescriptions for antidepressants and tranquillisers. Few are permanently cured.
Psychiatric knowledge is riven with dissent. Just how do psychiatrists justify their diverse treatments? Director DAVID CROSSMAN Producer UDI EICHLER

Dobsey Twins Isolate Radium

Dear Radio Times,
Congratulations, the BBC, on producing a real winner with Alexei Sayle's Stuff. My two daughters and I have only one complaint: since we still possess a 405-line television set, we find the constant references to 'fat b*****d' somewhat baffling as the gentleman on our screen is in fact rather slender and well proportioned. Is this a joke for the benefit of 625-line viewers? If so, don't you think you should spare a thought for all of your audience?
Mrs L. Minnow, Lincolnshire
Alexei Sayle replies: Who gives a damn what you think?

Featuring Alexei Sayle
With Angus Deayton, Tony Millan, Felicity Montagu, Harriet Thorpe, Mark Williams
