The GP is left holding the baby after upsetting the new childminder, but luckily Mike agrees to look after James at short notice. However, Louisa is not happy with the arrangement and an argument erupts between the newlyweds just as their guests arrive for dinner - and that's only the first of the evening's problems.

With Louisa visiting her mother in Spain to get some perspective on their marriage, Martin knows he needs to try to change for the sake of their relationship, so he endeavours to keep his promise to her to see a therapist. Aunt Ruth arranges an appointment for him with Dr Rachel Timoney, but a lifeboat training exercise causes problems for the doctor. Will he get back in time for his first session?
