A man with dementia is brought in after suffering a bump to the head, and after giving the staff the runaround he finally settles down thanks to Connie. But as his condition worsens, can she save him? Jeff and Tamzin are called out to a party where the boiler has exploded, putting intense pressure on an already busy department as an influx of revellers turn in the ED. Ethan and Rita suspect one of the partygoers of being bulimic, while a frustrated father is forced to leave without his ill son being seen.
