When Roy and his wife, Joanne, have a fight, John helps them out, which makes the situation worse. During the rescue of a man whose car is hanging over a bridge, the erratic instructions and behavior of a new doctor, Dr. Varner concern Dixie. Dr. Varner later catches an atrial myxoma, that Drs. Early and Brackett had both missed, but she then is found asleep in her car, and Dixie learns the reason for her behavior. The firefighters assist a man who had fallen off a roof trying to get his dog down (then they rescue the dog), and two children lost in a rapidly flooding storm drain.
