At Putneymead Group Medical Practice in south-west London, Dr Alison Kirkland sees a woman who blacked out while walking home from work, while Dr Mandeep Baveja tries to discover the root cause of his patient's crippling back pain and inability to control his bladder. Nurse Louise Johnson is doing her best to look after a mother and her three children who were run over by a van, and Dr Kieron Earney and his patient discuss which provides the better service - private health care or the NHS.
