Rita's son Lenny comes home from Afghanistan just in time for Thanksgiving, but the happy reunion is put on hold when he ends up unconscious and temporarily paralyzed after a motorcycle accident. As Michael preps for the risky operation, Rita and her husband struggle over the question of what would be best for their son if he were to need a machine to stay alive. At the Clinica, Kate and Zeke intubate and bag a near-unconscious man who is brought in by a bus driver. But after stabilizing their patient, the doctors find a "Do Not Resuscitate" bracelet in his coat pocket. Since no hospital will take a patient who was revived against his will, Kate and Zeke take turns pumping the bag while deciding what to do next.
