Mr. Toller is a man of immense personal ability. A self-made man who has no time for the weak or the idle. A man without humour. A man indeed who creates hatred. Jo Hardy is treating Toller for some inexplicable illness. The patient makes it no easier for Jo by his overbearing arrogance but she patiently tries to diagnose what is causing his illness, which becomes more and more serious. Guest stars Peter Vaughan and Gilbert Wynne.
