As dysentery sweeps through the area Trixie takes on her first official duty since her engagement to vicar Tom by organizing the Rose of Poplar contest whilst Phyllis is concerned for sickly Dolores McEvoy, who is living in a filthy hostel apart from her husband but is too ashamed to give the address. When Phyllis locates the hostel she also finds the source of the dysentery. Meanwhile young father-to-be Tony Amos is the victim of police entrapment when he goes cruising in a men's toilet. Dr Turner speaks up for him when he is taken to court but, although prison is avoided, bigoted attitudes make life difficult for him and his wife and the nurses' opinions are divided.
