Alex accidentally provokes the Emergency Department's mean girls; Ron and Serena battle over parking etiquette; Bruce has a hard time letting go of the spotlight.

Joyce launches a women's health initiative to unexpected results; Ron treats a patient who has all the answers; Bruce has an existential crisis.

It's the holiday season at St. Denis; Alex and Ron care for a patient whose diagnosis is not what it seems; Joyce enlists Serena's help to boost St. Denis' online presence; Bruce and Matt help a Santa in need.

A storm causes chaos in the Emergency Department; Alex is torn between an obligation to her husband and her co-workers' needs; Joyce goes on a spending spree with found money.
