The entire first series of the BBC medical sitcom following the fortunes of the staff on an NHS hospital ward. Beset by killer viruses, egomaniacal consultants and endless paperwork, the overworked and underpaid staff of ward B4 struggle on regardless. Snowed under by her workload, neurotic Ward Sister Flixter (Joanna Scanlan) is forced to rely on the talents of seen-it-all-before nurse Kim Wilde (Jo Brand), while trying to avoid the attentions of over-egging Ward Doctor Pippa Moore (Vicki Pepperdine).
In the first episode, a patient's daughter ends up requiring more attention than her elderly mother. As the series continues, an incident on the ward leads to a disagreement over who is to blame; Kim's hopes of a quiet night shift are dashed by an emergency admission; a graduate nurse drives a wedge between Den and Kim; and Pippa considers life away from the ward.
