A documentary crew visits the hospital, exciting the creative juices in Alan and the bitter rivalry between Sue and Joanna. Meanwhile, a tape of Guy being "intimate" with his mother is now in the possession of Sue who plays merry havoc with his and Joanna's life. And is this the end for Angela as she falls for the charms of the director who's off to Toronto next week?

Dr. Statham enters politics but requires a voice coach and the use of a car with two loudhailers! Martin inadvertently becomes a pimp. Mac and Caroline get a little closer but Holly sticks her oar in with a little ginger surprise for Mac. Harriet and Lyndon manage to have a date despite Joanna's best attempts to sidetrack her with work. Guy is not exactly the best flatmate but is he there at the right time for Caroline?

Mac adjusts to his new rôle as a father while Caroline tries to make him jealous with Guy. Statham is rather pleased with himself for winning his radiologist's community weekly caption competition which does not please Joanna. She employs her vertically-challenged cousin to scare him but a trip to the incinerator is soon required. Martin pesters Joanna for knowledge of his dad and hires a detective to find him.

Sue does some detecting; Martin comes into some money; Statham and Joanna try to keep the incident with the stuffed heron secret; Caroline has to be cruel to be kind.

Demented dwarf killers Joanna and Dr Statham are amazed that they seem to have got away with their hideous crime so consider themselves above the law. Caroline gets no fewer than three proposals. Sue gives birth to an infant with a mane just as impressive as Mac's. Mac gets some bad news while Martin (and we the viewer) ends up with a strange sense of déjà vu in the season's cliff-hanger ending.

Caroline engaged to Guy, Mac getting closer to death, Statham and Joanna on the run, Karen acting strange and the admin girls letting their hair down a bit lower than normal.
