Mental health is a vital public issue for doctors to address. Dr McLaren meets a young man seeking help because he is hearing voices. Dr Hardy meets a new patient who has a number of handwritten notes that he can't remember compiling, while Dr Pelly is delighted that a patient is responding well to treatement for schizophrenia.

Patients include an ex-prisoner who has fallen back into drug addiction, a man with an extremely painful groin, a pregnant lady with painful ears, and a young woman suffering from extreme tiredness, dizziness and episodes of uncontrollable shaking. Plus, the doctors consider the many challenges facing general practice in Britain and what the future might hold.
