Christmas Eve. Finally, a few days off after the busiest time of the year. For a while, everything revolves around cozy gatherings by the Christmas tree, enjoying a lavish Christmas dinner, unwrapping presents, and eating Christmas cookies. But not for everyone; for the emergency room staff, work never stops. The hospital doesn't have a pause button to relax. On Christmas Eve, the night shift has only just begun for Lily, Ben, Yannick, and Shanti. Even though they're certainly not there for fun, the world outside the hospital walls has little to offer. They've all fled Christmas Eve. To prevent worse from happening.
