After five miscarriages Niamh's patient Kara Meredith has persuaded her 50 year old mother Diane Larkin to be her surrogate. But trouble arises when Diane, who lost her son in an accident some years earlier, decides she wants to keep the baby for herself and Kara's angry reaction comes close to jeopardising the birth. Heston meanwhile feels that he is having too many senior moments and Emma is surprised to find Adam teaching Karen and Mandy yoga in her house.
