Portwenn looks set to become a hotbed of passion. Louisa Glasson is furious to discover she has a rival for Doc Martin's affections: glamorous divorcee and hotel owner, Carrie Wilson. Can Louisa contain her jealously and claim Martin as her man before Carrie's flirty tactics take effect? On his way to PC Penhale's birthday party, Martin accidentally reverses his car into Carrie's dog, killing him. Carrie is distraught by the death of her dog and slaps Martin across the face when he hands her the dog, and tries to apologize.
