Dr Sara Kayat meets Daya, a young man who has been experiencing trouble with his feet for the past four years. He has what appears to be a fungal infection under his toenails, so Dr Sara takes some clippings to send off for analysis. Her next patient is Anna, who has been driven to distraction by itchy feet, caused by athlete's foot and pustular psoriasis. Plus, Dr William Laird takes the surgery's third foot patient, this time taking the form of schoolboy Jack, who sprained his ankle during enthusiastic performances on the squash and volleyball courts.
