Elderly patient Brian arrives concerned that his feet have turned an alarming shade of blue. But Dr Williams seems more worried about his low mood. A man arrives after an episode of abdominal pain so severe it made him vomit and seek help in A&E the night before, while a woman is suffering insomnia, which in turn may be triggering depression. Nurse Rosie issues a warning to patient Pat when her blood tests reveal her sugar levels have skyrocketed and Dr Arif treats a baby with constipation.

Dr Razak's first patient of the day is Muriel, an elderly woman who recently suffered a mini-stroke. She is reluctant to take her blood pressure medication because she has an aversion to drugs - but as the doctor explains, not doing so could make things even worse. Elaine asks Dr Costigan to give her painful knee a once-over and 92-year-old Elizabeth comes in for her regular heart check-up.
