Doctor Flynn starts working at the south Middlesex hospital. He suffers from a series of nightmares, which stem from the complicated operation that caused him to fail his finals first time. Doctor Noble tells everyone in the hospital, and Flynn becomes a laughing stock. A new patient is admitted who sells coffee… a much-desired drug around the hospital, one which Noble swapped Flynn's personalised stethoscope for. To gain the respect of the staff, Flynn makes everyone in the hospital a cup of coffee, only to find out that it is de-caff! Flynn becomes convinced that the coffee rep needs the operation that he failed on, and does it, puncturing the patients lung, just as Mr Ron comes to do the rounds…
Flynn tries to learn stitching to impress Judy. Flynn gets locked out of his flat, and is told to sleep in casualty. He begins to treat an old lady (Ethel) with a bowel obstruction, who bites his finger. His finger is treated by Judy, who teases him into taking his trousers off, then gives him a tetanus shot. While Flynn sleeps on a trolley, Terry and Judy get him sectioned. In the morning, Flynn escapes, and meets Noble, who tells him that the old lady was only constipated, and he has given her laxatives, so that she will ‘relieve' herself at 9 the next morning. In search of a toffee, Ethel grabs Flynn's left testicle. He also find that his door has been ‘fixed' by being pulled off its hinges. Flynn stops Ethel's sleeping pills, causing her to go on a zombie-esque rampage. Judy flirts with Flynn, and tells him she might sneak into his room. As he sleeps, she sends Ethel into his room. Everyone gathers and wakes Flynn, just as the clock strikes 9am…
