On the road, Cate and Mac are called to attend a young sex worker what has been severely bashed at a brothel. Cate is profoundly disturbed when she sees a young girl in a room with a man. She reports it to the police who are unable to do anything without evidence, so Cate drags Mac long to investigate the young girl herself. When the passengers and crew of a cruise liner fall ill with suspected food poisoning, Frank volunteers Jack and Terri to go down to the ship and help assess the medical condition of those affected. Terri's impressed with the way Jack takes control of the situation, but things soon sour. When Jack realizes one of his patients has a child illegally stowed away on the ship he asks Terri to smuggle the child away from the dock and back to the hospital. Terri reluctantly does so, but if she gets caught her job will be in jeopardy. Amongst the chaos of the Emergency Department a new face returns. Andrea Stuart, All Saints Public Relations staffer, is greeted warmly by Terri after a three-year absence. In an effort to help bring him back into the team, Terri appoints Nelson as Staff Educator. Embracing his role a little too zealously, Nelson soon alienates Dan and Jessica and finds himself on the warpath with Frank.
