There's a new doc in town. His name is James Peterson (guest star Matt Long). He's taking over the spot in the ER that used to be filled by our deceased friend Pete. James picks one of those rare rainy days in Southern California to begin his first shift. It's a busy one indeed. All of our other favorite docs are called in to serve an overflowing ER because, well, no one in L.A. can drive in the rain.
James treats a young girl, Sarah, who comes in with a fractured wrist. He suspects the injury may be a result of abuse. Cooper disagrees with this theory, as he knows the family well. He convinces James to let him make a call, which he does. Only it's not to the proper authorities. It's to Violet, who learns that the little girl's mom and dad are fighting all the time. It makes her want to run away from home.
Violet advises Sarah's mom and dad to stop fighting in front of her, as it's doing some serious damage. This is moments before the parents return to their child's bed to discover that she's not there. Her raincoat is gone. Sarah's mom hysterically searches the ER area. Charlotte puts the hospital on lockdown. The search is on for Sarah.
