With her 30th birthday fast approaching, Kate worries that her age is starting to show in the most unusual of places. She is happy about her budding relationship with new registrar Dr Peter Compton, despite the ridicule she gets from Beth and Lia when they realise she and Peter haven't had sex yet.

The nurses at St Margaret's are feeling increasingly under threat from violent patents. Unimpressed with the new, prepubescent security guards, Peter uses his army training to give self-defence lessons to the rest of the staff.

Kate's mother, Valerie, surprises Kate with a special birthday visit. Unfortunately, Valerie is more interested in joining Lia and Beth on a boozy night out than spending quality time with her daughter. But Lia and Beth have a surprise - or two - in store for Kate.

Anji is home, is pregnant and has picked up a newfound spirituality on her travels so seems entirely unconcerned about the practicalities of having a baby on her own. Reality bites when she applies for her old job as an HCA. After trying to offer the baby to her sister, Anji comes up with a plan to find her best 'conquest' and tell him he's the dad.

Meanwhile, single parent Lia is asked by her daughter Emma to go to a craft evening with her. When the group leader points out that Lia and Emma have 'communication issues' Lia decides to take action.

Beth takes offence when Steph, the insecure girlfriend of a good-looking male patient, Patrick, has a go at her for flirting. Beth decides to teach her a lesson and while tending to Patrick's wound, deliberately glues herself to him. Stuck together for 24 hours, Beth uses the opportunity to wreak more havoc for jealous Steph. She tells Patrick there is nothing a woman likes more than total honesty, even when it comes to secret male fantasies. Little did she know that in this instance, honesty really is the best policy.
