The day of Nelson and Kerry's wedding sees the ED filling up with victims of a chemical explosion in a paint factory. As multiple casualties arrive, the team is forced to put aside well wishes for the happy couple as they deal with the traumas the explosion has given rise to. And the entire team is given a lesson they won't forget in a hurry life really is too short. Dan finds himself nursing a young man with serious eye injuries. Bad enough that the man may never see again, but today his first child is due to be born and the thought of missing the birth is devastating. A teenager arrives in the ED with serious injuries and a terrible secret. Thank God for the cheery fireman, Michael, whose optimism and high spirits bring a smile to this terrible situation.
