The gripping, darkly humorous and disturbing medical drama continues with more explosive action and emotional confrontations - the personal and professional loyalties of staff at South Central Infirmary's Obstetrics and Gynaecology Department are tested as never before.

Registrar Rob Lake (Max Beesley) finds himself caught in the bitter rivalry between his dangerously incompetent boss Roger Hurley (Patrick Baladi) and bullying consultant Tony Whitman (Keith Allen). Will ambition silence him, or can his sometime lover, Sister Donna Rix (Neve McIntosh) persuade him to take sides? And it's crunch time for Rob's career and love life as he and fellow registrar Polly Grey (Tamzin Malleson) fight over a new job.
