Rob Lake starts work at the Obstetrics and Gynaecology Department at the South Central Infirmary as a new registrar. There he encounters problems from the start including one woman who almost gets the wrong operation after a communication error.

Later, things go from bad to worse after a woman dies when Rob has to perform an operation on her throat that he isn't trained to perform! Also, Dr Maria Orton approaches Rob about his supervisor Roger Hurley who she believes is incompetent and only got his job because of the amount of research he does.

Karen Taylor is admitted to the ward. She is bleeding internally and requires an operation. Roger performers the operation but things go wrong. Karen is left brain damaged and her child ends up dead and the baby's father, Karen's husband, wants answers.

When another of Hurley's operations starts to go wrong, a desperate Rob persuades Whitman to intervene. But what will the consequences be of his betraying a fellow doctor?

Fast-forward three years and a lot can change. Rob Lake's got a new position in a different hospital. And he is about to become a father. But one thing remains the same -- Dr. Roger Hurley is still practicing.
