While the Angels Memorial staff scurries to take care of the high-risk patients including a pregnant women in labor who is trapped in an elevator with residents Elliot (Noah Gray-Cabey) and Heather (Jillian Murray), Dr. Ethan Willis (Rob Lowe) and psychiatrist Dr. Amanda Nolan (Kathleen Rose Perkins) must transport a fragile 92-year old patient named Blanche (Barbara Bain) to another floor where she’ll be in better care.
