Dr Sam Morgan arrives in Cardale as David's locum. He is thrown straight into the deep end when he has to tell a pregnant patient she has cervical cancer. Joanna has dinner with old flame Martin Henderson and gets a lot more then she bargained for when it is clear he is still in love with her. Meanwhile the romantic tension between Andrew and Dawn is brought to the fore.

Dawn throws herself into organising a barn dance to raise money for the community hospital. Andrew and Joanna lend a hand and the evening looks set to be a big hit. Elsewhere there are complications for the Sinclair's when Alison develops a blood clot. Sam prepares them for the fact that their baby has to be delivered now. However not even Sam is prepared for the shock that lies around the corner.

Dawn is affected when a patient requests a referral for breast implants. She is unnerved when Andrew agrees with Joanna's referral and wonders how he would fell if her breast cancer were to return.

Claire arrives back in Cardale and announces she is selling David's share of The Beeches. As David owned the larger share, The Beeches looks set to fold unless Andrew can convince Joanna to become a full partner in the practice.......
